2003 Honda Civic - Ignition Lock Cylinder Replacement and Key Reprogramming

[@mikeydstar01]

Thanks so much, this helped me alot, my key was jammed in the ignition, unable to get off the 1 position. I brought another ignition key set from ebay for £25. As I cannot be bothered to pay for reprogramming - I use the original key now just to set the immobilzer and the new key to turn the ignition. Using a dremel drill to cut slots in those bolts was a real nightmare but it worked.

[@jpwns360]

How do you do that exactly? Sorry I know it's an old comment but I'm having the same issue. Do you just slide the old key in and take it out and turn with the new key?

[@mikeydstar01]

@@jpwns360 yeah it was a nightmare!! I had to buy another key barrel set from eBay. As I did not have the money to have the new one reprogrammed I ran it with two keys. I key just told the car I had the key as it was jammed in the barrel the other key was used to start the car. The MOT people failed it for this reason claiming it made it dangerous to drive. I must admit it was a bit clunky. Still I have a keyless ignition car now

[@james110100]

The security bolt can be loosened using a cold chisel to tap it around. The new bolt has a hex extension which snaps off after tightening.

[@StevensAngel123]

Does the scanner have to connect to the vehicle any type of way, or does it just guide you through detailed instructions?

[@samcarr4875]

Update: In my case, once I got the ignition cylinder out (the difficult part), I was able to narrow the issue down to some damaged tumblers. A local locksmith had them in stock and replaced them in about an hour for $50. Hopefully this saves some others from having to buy a new whole new ignition cylinder. And +1 to using a center punch on the shear bolts. I unsuccessfully tried to cut a groove to take one out with a flathead screwdriver which took about an hour, them found the center punch method in another video and had them out in 5 minutes.

So had a mechanic mess around with my ignition area where my key inserts in And he took out a few “mini keys” out of it to get my key to turn again…. Now this green flashing light keeps coming on & car won’t start. To I need to have my keys programmed back to the car?

[@missadda8890]

I tried to chisel the no-shear bolt but I stopped and used a C6 punch and a drop of WD40 came loose after a few taps I am going to take it to a locksmith to fix the tumbler I have a 2004 civic vp no fob just a key that only goes halfway in due to a family member trying to start it with a Subaru key by accident🤞

[@fieldsofomagh]

Interesting procedure.Let me see, off then on, on then off, off then off and then I got me a reel in my cerebral dept.Say to yourself " i must not lose my keys" Merry Xmas all good mechanics out there !!

[@ThEsM0kEch0kE]

Does the battery need to be disconnected before replacing the ignition lock cylinder for the bolts where the clamp is?

[@seanyutah]

i just got a new ignition lock cylinder from another civic and it came with an immobilizer unit. Should I use this new immobilizer unit or replace it with the old one?

[@johnathanmagee1643]

I got one from another car I still couldn't get mine to start

[@depdark1]

So if i cut the end of the old key and tape it to immobilizer unit and use the new key to unlock cylinder . Will it work ? 🤔🤔

[@xxxsanyeo]

probably but of someone has a car lock pick they could wasily steal it

[@depdark1]

@@xxxsanyeo thats true. I end up removing all the teeth of the cylinder and sold the car moths later

[@richardmeier2558]

Is there a way to bypass the immobilizer so that the car will turn over

[@gato7035]

just have a question I replace the ignition cylinder from another car with a different key but I am using the original Immobilizer Why it not starting any suggestions thanks

@@mgtow6450 f__ you!

[@floridabornandraised1803]

Some new ignition lock cylinders doesn’t come with a new immobilizer unit , mine didn’t. You would want to use the old immobilizer unit anyway cause I found an easier and cheaper way. And that is a immobilizer unit that he pointed to. I found it a lot easier to just change the inside of the old key fob with the new one. You can buy one with the extra holes if the new key fob doesn’t come with the proper fit. Or you may be able to make extra holes in the new fob, that’s what I ended up doing. I didn’t need to do anything else cause the old immobilizer unit and the inside of the old key fob works together. Saved me a lot of time and money. No green key light, car started up fine and no programming at all. Door locks worked fine. But I did keep the old key just in case I needed it to unlock the doors or trunk manually.

[@samcarr4875]

Where did you buy the new ignition lock cylinder? Everywhere I'm finding shows it to be $300-400, which seems like a lot for an aftermarket part

[@MattsMotorz]

I bought mine on rockauto.com and yes it was about 300 bucks unfortunately :(

[@samcarr4875]

MattsMotorz OK, thanks

[@Dreday-pw3fi]

I can't find the immobilizer option

[@mxkcrm]

Why did you replace the switch in the first place? My neighbors 01 civic doesn't crank over, good battery and starter. Key light doesn't flash, should I replace the ignition switch?

[@soglenn]

2004 Honda Civic Coupe: swapping out a DX Engine to a HX so i will have ECU and have the key that goes with it. Is it possible to get the key to work without going to the dealership? Or will I need to replace the immobilizer ring in my car with the HX one that matches the key and ECU? Just want to know the easiest route. Also, do you have the link to Ivan's channel?

[@fun_ghoul]

You said you'd have the HX key and ECU, but didn't mention the immobilizer box. Without that, you will be (or, by now, will have been) programming a new one to the key.

[@richardmeier2558]

Hello have a question someone tried stealing my car and they wrecked my ignition but they couldn’t start it ,the vehicle worked before this incident noticed that the connector motherboard that’s wrapped around the key is broken .is that problem why it won’t start now and how can I fix or bypass it ,the car still turns over

[@siachen6680]

Can you buy the lock cylinder only instead of the whole assembly?

[@fun_ghoul]

Yes. I think they have them on Aliexpress. Definitely a good way to go if your switch works fine. For that matter, once the cylinder is out, it's easy to get inside it and either replace or (shhh...) _remove_ the sticking wafer(s). Reply if you have questions. Good luck, saathi.

[@xxxsanyeo]

can you just pull the transponder out of the old key then put it in the new key

[@Karen-db6bc]

Help! My husband just installed a new ignition in a 2005 Honda Civic. But, the keys that came with it will not turn at all. So, no dash lights. Was told we need to have a locksmith come out to unlock it, THEN take it to dealership for programming. Any advise as to why the new keys won't turn? Tried everything. Thanks

[@MattsMotorz]

That sounds odd to me. The keys should turn it. Take it out and see if it turns with it off the car. Perhaps it was installed incorrectly. That's the only thing I can think of. I haven't done much of these. You absolutely need it programmed though. That requires a locksmith or going to the dealer (or knowing someone with the right equipment like I do!)

[@Karen-db6bc]

MattsMotorz First, thanks so much for getting right back to me! Your the only one who even responded. Do you mean to take out just the switch or the entire ignition? My husband said that removing the whole ignition will ruin it because of the break away screws.

[@MattsMotorz]

Damn I forgot about those screws. Try turning your steering wheel as you turn the key. Sometimes the steering wheel lock gets binded up from the steering wheel torqued to the side while its locked. Turning it back and forth while turning the key fixes that.

[@Karen-db6bc]

MattsMotorz I'm wondering if that's part of the problem. The steering wheel won't lock in any position.

[@Karen-db6bc]

Woo hoo! Did more research on why the steering wheel wouldn't lock. Someone suggested the steering wheel pawl might be stuck. My husband gave a couple of good whacks with a rubber mallet underneath on the metal and voila! Everything works, just need to program the keys. Hope this helps someone else. Thank you for your time and feedback.

[@glendonsmith5198]

Tell me if there are any type of simcard come with this ignition

[@redxsk8er]

that process of programming the keys, i do the same for my honda or is it different for mine?

[@fairweatherfoundry715]

Same process

[@mil7onautodiagnostics633]

do you know If I could reprogram key with spaon verus?

[@01cissy]

I have an 04 civic ex sedan manual trans. I needed to replace the ignition lock cylinder and had to have a locksmith install it in the cylinder but works fine now. my problem now is getting the wire harness )male end) on top of the steering column back into its female slot. It acts like the f end is to small for the male end to fit into. ( OK, NO pun intended ! ) Help !

[@TactMod]

Hi. TY for the Video, it's very informative. QUESTION!: Can I put an 02 or 03 Ignition cylinder, with new door cylinders in my 2001 Civic LX ? Im having a hard time finding one for my year... Thanks in advance. =)

[@fun_ghoul]

Definitively, you can put the ignition switch assembly in any 01-05 Civic from any other, as long as you use one with the interlock switch for an automatic. This means you can "upgrade" to the shitty "high security" keys if you like the look or want a shitty Chinese flippy Fobik, or _actually_ upgrade your 2003.5, 2004 or 2005 to the older and superior HD106. Of course, if you switch types, you're stuck with 2 keys until you change your door/trunk locks.

[@jesnbel4111]

Will a automatic ignition lock cylinder fit into a manual ? My local pick n pull only has automatics and I need to replace the ignition switch.

[@BIGWEEDON]

Can a lock smith do the programing... Because I don't want to mess with the dealership

[@MattsMotorz]

I believe so yes.

[@kemald272]

I'm having an issue with my 02 civic. When I try to start it early in the morning nothing happens. I have to play with it for a bit. After turning it to the on and off position for a while it will eventually start. Only happens in the mornings. Would replacing the key lock cylinder fix my problem?

[@MattsMotorz]

It is impossible to say. What should be done is to use a multimeter throughout the circuit (with the help of the wiring diagram and the factory service manual) to see where you are losing the connection, starting at the lock cylinder itself.

[@polivares456]

Excellent video

[@franlowrimore6612]

where can I get that computer tool to do that myself

[@MattsMotorz]

Just google the name of it. It is VERY expensive though. On the order of $1,500 bucks or more

Soo do you absolutely have to put on the old immobilizer unit to the new assembly?

As well*

[@hhelmejor5485]

yea, I know, the guy does a flash number on using the old immobilizer; what a jerk!

Don't make sense to use the old unit if you have to reprogram it anyways

[@wdbne00]

My honda blows extremely hot air inside when the heater running. But the temp gauge reads normal. The upper radiator hose is hot but the lower is cold.. i replaced the thermostat with a new factory one. But still didnt fix the issue. The radiator fluid surges up and down when running. But when i take thermostat completely out and run the car both radiator hoses heat up normally. I cant find any helpful vids on this issue so could someone give me some ideas.. thanks. Also i have replaced head gasket, water pump, timing belt and radiator... dont know what else to do??

Will any scan tool work to program new keys?

No not all scan tools have that feature.

[@NewLevelAuto]

Hey just a heads up that Astral Auto that you are allowing to show your videos also had videos showing our mutual friend Ivan in a negative light . Specifically referred to as the dysfunctional family and on a "Banned video " . You would be smart to disassociate with them before they turn negatively on you as well. Just a heads up .

When you buy a car back in 2003 do you get 2 keys

[@petar443]

So you are the transmission man?

[@johngeyman6054]

EZ out

[@MrRShoaf]

Allow me to crangratulate you on scrapping a lock that should have been repaired. First, the cause of the locks failure was due to the key wearing to the point that the tumbler (s) were forced sideways and jammed rather than sliding up and down. A locksmith could have made you good keys, replaced the worn tumblers and transfered all of the trasponder chips to new keys. Doing it that way would have kept all your locks on one key, and prevenred the old worn keys from killing the door and trunk lock.

[@TravisBiggie]

lucky me, my friend is a locksmith and he is going to be doing this for me soon. I just removed the cylinder lock today.

[@hhelmejor5485]

hmm, I thought in the scenario you pose, the new keys have to be reprogramed but now the transponder chips have to be transfered .. drip, drip WTF?

[@MrRShoaf]

@@hhelmejor5485 Yes. They make key blanks that have a pockets where the chip can be inserted.
