Opel / Vauxhall Key Fob step by step Repair guide and battery replacement.

[@nikitos19872005]

*This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, **batery.repair** and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!*

[@istvanliptak8328]

Thanks. You helped me realise that the transponder is missing when the key had been dropped to pieces, and the car did not start afterwards. Lucky the chip was on the seat :)

[@AndBor1]

Thanks a lot. Last time I tried without seeing how it was done I ended up breaking half the case and I had to reorder it after losing lot of time (thanks God I looked into eBay and not Vauxhall extorsionate process). This time, 2 minutes, all done perfectly without any problem. People like you is a Godsend! Thanks!!!

[@CB-RADIO-UK]

Your welcome, easier when you know how :-)

[@1066gaz]

Thanks for this great video. I had one key that unlocked the doors but it did not work the immobilizer. The other spare key worked the immobilizer but not the doors and i swtched the key part around and voila the key now worked the immobilizer and the doors and the other one is now completely knackered. So thanks for letting us know that the transponder is in the detachable key itself. Saved me £30 fred cheers.(;-) Update... Just realised what was wrong. With other key the transponder chip had come out of the key end itself i thought it was inside the key itself and not accessible but not the case it comes out easily. I put a new battery in last night and this morning the car did not start and realised the chip had fallen out when i replaced the battery and put it back together again. I found the chip in the bin must have got there when i did the hoovering up later on,luckily i found it and it was in the middle of the bin on top of some empty walkers cheese oven baked crisps lol. First time in 15 years that i noticed it had this small chip and it was tucked away and must have been held in with glue or something as it falls out very easily now and with the other key it does not. Also i might add you have to put the key in the ignition and press the remote key to pair it to the car otherwise the key won't remote lock/unlock the car doors. My car is an astra g 1999.

[@ziopinoo71]

Thank You very much! Your tutorial is very clear and simply to follow. My Opel Corsa C now has a "new" perfect repaired key spending really "nothing" in comparison with full original key replacement from opel (50 euro in Italy!).

[@CB-RADIO-UK]

Your welcome. I know a gen Opel / Vaux replacement is a rip off.

[@jonathanholden412]

Brilliant film- just bought key from eBay for son's Corsa and your film was spot on ...saving me £87 from Vauxhall!

[@HandsomeMoose]

A tip. When you have put the button side together - test the buttons. I bought a kit from AliExpress for less then 3 $. Worked fine. Only problem was that when I was done I found that the "Lock" key did not work. The reason was that the new part had a small plastic "nob" on the inside that was so big that it stoped the button from working. After I filed it down it went better.

[@KG-ul7nx]

You're a lifesaver Fred. This helped me out a lot today. Exactly what I needed. Thank you!

[@jayholroyd9523]

thankyou for a very simple and easy step by step video! I changed my fob in less than a few minutes!

[@mikeashton8368]

This video is excellent. I worked through the procedure stopping and starting the video. Success! Purchased through Amazon at £2.19

[@CB-RADIO-UK]

+Mike Ashton Well done mate you have saved yourself a packet.

[@deanchetty4093]

Thank you. I broke my key and used this video to repair it

[@trf223]

0:38 I found it helps to twist the flat head screwdriver when pushing in to remove the cover.

[@Zipy88]

Thanks for the video. It's really useful. Can you give me any advice what to do if the buttons are too sensitive and when you bearly touch the the car goes crazy with lock and unlocking?

[@CB-RADIO-UK]

You might try cleaning the buttons with some contact spray. Its odd as they normally go the other way.

[@niamhekins]

One of the buttons on my vauxhall corsa key has the broken (the lock button) and you can feel that it isnt clicking - will this tutorial work for that issue or does this only work if your buttons work before repalcing the casing?

[@Tobinindustrial]

Another great "How To" video Fred. Real nice tutorial as usual. A great cost savings by going this route for sure. Thanks for sharing once again.

[@CB-RADIO-UK]

Andy Tobin Thanks Andy.

[@verabolton]

Very helpful video with clear instructions. Thank you

[@raeesahpatel9388]

Thanks for the most informative vide. Just did mine in 5 minutes.

[@CB-RADIO-UK]

Pleasure. Well done thats saved about £50

[@Pibsie]

Thank you! Saved me so much time and so cheap

[@angelak6244]

I’ve changed the battery (nice and clear, ta) but it doesn’t flash and I’m still unable to open the lock remotely. Any ideas what I can do? Corsa 2004, thanks.

[@CB-RADIO-UK]

Prob the switches have failed. You going to need a keyfob rebuild or at worse a new fob. Sorry.

[@irene14117]

Worked a treat thank you

[@acemughal6967]

I have vaxhull mariva 2003 and key fob not working went to vaxhull showroom and they asked £120 too much if you ask me so I changed battery myself but not helping what should I do?

[@CB-RADIO-UK]

Try locksmiths as they offer a repair / refurb service normally for around £60-90. Sometimes they can reprogram it to your car as well.

[@shaun27ful]

Great video buddy, I had a similar problem on my old Peugeot, but I only had one master key for it, so I was advised to take the mobilising transponder out of the key itself and glue gun it around the key transponder in the car. Because if I lost my key Peugeot was going to charge me £257 for a new key and transponder and as you know, you only need really the circuit board and the key. But great video buddy sure it will help people.

[@CB-RADIO-UK]

shaun pi Thanks mate. Yes new programmed transponder keys are super expensive.

[@ChaislifeisFAB1]

I have one key for my car and I bought new locks because the out door locker were broken. Is there any way I could take the chip out and put it in my new key instead?

[@mascotty02]

Hi, I have been quoted £35 for a replacement, the button is the only thing worn can I change the fob myself, it all works still except you have to press hard on the lock button, I have a vauxhall Astra 1.6i SRi 5D... info on this would be appreciated and thanks

[@bluefantasy88]

great video! thanks for posting it! the only thing is that i need to move the two old little battery terminals into the new case and while i can easly do one, i have no idea how to pull the other out. Could you make a video for that please?

[@CB-RADIO-UK]

bluefantasy88 Yes the second one is hard to remove. A tiny screw driver helps. You will most likely break the plastic lugs on the old case bottom getting it out, its fiddly. Tbh unless the old case bottom is really rough it might be an idea to use that with a new top. The cars my daughters and she wont be impressed if I rip her fob apart, sorry buddy no video. ;-( Best of luck

[@dingb473]

just fitted mine £3 from eBay nice and easy job done

[@CB-RADIO-UK]

Aliyah. No I used the old bottom part as its hard to remove one on the metal battery connectors without damaging it.

[@aaliyahkhan2030]

oh okay, thank you for the feedback :)

[@brad2807]

That bit where the plus sign is on the board where you said to clean , mine is scratched, could this stop the car opening by pressing the buttons?

[@CB-RADIO-UK]

If its been heavy scratched and worn off the board then maybe yes.

[@dank8489]

I've got two keys, one is missing the transponder part though, is there anything I can do? I've seen blank ones on eBay for a fiver, is there anyway I am program it is using my other key?

[@janineplimbley5101]

I bought a 2nd hand corsa and it has had a new key fob. I have problems with it where it doesn't open the doors. I have had a new battery fitted but am contemplating trying another. To me it seems it is the buttons themselves.

[@CB-RADIO-UK]

+Janine Plimbley Could it be that the transponder fob has been replaced but not programmed for your car ? If so its a trip to the dealers I am afraid as you cant do it yourself. The buttons do fail and you can buy replacements for less than £10 on ebay if you know anyone with real good soldering skills they can be replaced. Scroll down the comments as I sent a link to Harry Jenkins below as he had the same problem. Best of luck.

[@janineplimbley5101]

+fredintheshed1 It worked fine when I bought it. I even got the broken fob to use in emergency but one of the little bits inside have fell off. it still looks new except the bit at the back where you stick the screwdriver is a bit chewed up. I wonder if its electrical?

[@CB-RADIO-UK]

+Janine Plimbley Depends what has broken. If its the silver metal contacts strips which hold the battery then that's ok as you will get those with a new fob. However if one of the tiny buttons have come away from the circuit board that's a lot more tricky. It would prob be cost effective to re-shell the fob and have it repaired than buy a new transponder key.

[@janineplimbley5101]

+fredintheshed1 hiya. after cleaning the gold coloured terminals on the button side of the fob all seems to be ok now. It even works from a good distance aswell.

[@CB-RADIO-UK]

+Janine Plimbley Good stuff. The spring terminals come with a new fob case if you decide to change it. Perhaps pick up a new battery as it may have a leak, and a spare is handy to have in the car anyway. Just get a proper make like Duracell. Anyway glad your working. All the best.

[@jw200]

One thing is rubber, second thing are the small SMD buttons inside. Luckily i have 2 keys. One is better. But second has really bad buttons, i looked inside and they are pretty much broken. Will see if i can replace them. Just have to get right size SMD button. Soldering is not a problem.

[@CB-RADIO-UK]

jw200 Yeah they look surface mount. Fiddly but doable with a fine iron. best of luck.

[@CB-RADIO-UK]

+Mark Scott Sometimes the surface mount buttons on the board wear out. You need to strip it down and try it without the worn rubber. If the buttons are failing then I would get a new one for £35 as they are tiny and hard to replace.

[@Reocoker11]

My circuit board has a connector/capacitor not sure what it is broken off, any help?

[@CB-RADIO-UK]

You can buy the surface mount micro switches on ebay. If you have lost something on the board your prob looking at a new fob and re program at the dealer or mobile locksmith

[@Reocoker11]

@@CB-RADIO-UK Cheers mate appreciate it

[@sahhull]

My Vauxhall key fob has never worked. Its had new batteries, it just doesnt work. Ive owned the van for 15 years... I use the key. 3 years ago the central locking stopped working. Ive not missed it. The van has now done 483,000 miles! No rebuilds.

[@1oo1optimus]

I have damaged the button connector to the circuit board.. what do I do there?

[@CB-RADIO-UK]

If you look on Ebay the buttons are available. Problem is they a surface mount solder joints. Its possible with a low watt solder iron and steady hand you can replace them. If unsure there are some locksmith centers which offer a refurb service. Failing that its a new key and re program job from the main dealer.

[@simaofernandes7484]

I am going to replace the chip because after replacing battery it still doesnt work, what are the steps for sync the new chip?

[@CB-RADIO-UK]

If you mean reprogramming a blank key its a dealer or locksmith operation.

[@simaofernandes7484]

@@CB-RADIO-UK basically I replaced battery and it still doesnt work, so I think its the board that needs replacing but I dont know how to sync a new board to my corsa c

[@WestcountryDude]

Did the job for me. Thanks!

[@aaliyahkhan2030]

When you changed the key did you use the whole of the new parts or some of the old shell too?

Best Citizen watch out there. Poor man talked about a key😀

[@luketurner8623]

Thanks for this video! Very helpful! :)

[@jw200]

Fred. My Opel key fob doesnt want to open doors if im too far from car. I have to almost touch the car for the key fob to open the doors (central lock). Do you know how to make it work farther?

[@CB-RADIO-UK]

+jw200 Sounds like your battery needs changing. It should work from 20 meters plus.

[@jw200]

fredintheshed1 Already replaced with new. Both key fobs have same problems. Does internal central lock use some kind of antenna/wire. Maybe its broken

[@CB-RADIO-UK]

+jw200 I guess it must have but no idea where it would be. Have you tried a search on a Opel / Vaux forum ?. Normally if you have the problem then someone else has it also.

[@christreanor6637]

+jw200 hi,did you fix your fob? I work for Lookers yardley in the parts telesales. you could try this.....turn on the ignition(no need to start the engine just ignition lights on,on dash) then press either button on your fob, you might hear the sound it makes when you opperate the locks (like the button going up and down). If you hear this sound,it means it has reset. switch off the ignition,take out the key,jump out the car and try it! hope this works for you.

i have a small problem, you see the silver plates with the black rubber dot on the circuit board, i have lost them, is there a way i can fix or replace this.

[@CB-RADIO-UK]

harry jenkins You can get a repair kit for the micro switches from Ebay harry, guess your going to have to be good a soldering though. I cant place a link here but will add a new comment above.

[@harryjenkins2214]

i do have a soldering iron, how handy, thank you very much

[@CB-RADIO-UK]

harry jenkins Your welcome harry. If you search on ebay you can get just the 2 switches for about £2.50. It will be fine soldering though. Best of luck/

[@smurfiennes]

Thank you very much 👍👍

[@sulabhale667]

Im not sure if yu will still reply but will the key still be programmed as it will be disconnected will it still be saved for my car?

[@CB-RADIO-UK]

Yes the the key has a ROM chip which means it rems the code when you change the battery.

[@michaeldixon2882]

How do i remove the transponder chip?

[@CB-RADIO-UK]

A very fine solder iron tip and a big leap of faith.

[@addisatnafu4569]

Many thanks brother !

[@CallumG0161]

I have a problem with the actual button, it feels like it is broken under the rubber how would I replace this?

[@CB-RADIO-UK]

The buttons are available pretty cheap on ebay. The problem is they are surface mounted on the circuit board inside the fob. With a low watt solder iron and a steady hand it is possible to replace them but not a job for the faint hearted.

[@roxr4473]

I replaced everything, but the buttons are so hard I can barely touch them. Is this normal or...?

[@CB-RADIO-UK]

Did not find that with ours ? Our buttons were a thick rubber ?

[@davidevans7835]

How do you put new buttons in

[@CB-RADIO-UK]

Its fine surface mount soldering. Repair Kits are available on ebay but you are going to need a fine soldering iron.

[@tmaciejs]

How programme the kay again after replaced battery ??

[@CB-RADIO-UK]

You dont need to the key has a ROM chip so it remembers the code.

[@tmaciejs]

Thank you, probably I have damaged my key because it still does not work. I bought new key 433Mhz and I used FVDI diagnostic cable to read my PIN code but I don`t know how to programmer new key, I mean keys button to open and close doors ( fobik is old ).

[@CB-RADIO-UK]

Only way i know is to get the dealer to reprogram the key or one of these mobile setups. I think you need the hardware. Sadly not cheap.

[@stasksmac3497]

thank u ,just done mine
