Honda Jazz (Fit) Mk1 (2002-2008) - Remote Central Locking Upgrade

In this video we attempt to install a cheap aftermarket remote central locking (keyless entry system) into a 2003 Honda Jazz UK spec. These kits can be purchased for around £10-15 from places like Amazon & eBay.
As usual always take precautions when working on car electrics like disconnecting the battery.
Here's the wiring diagrams to help:

For everyone with a USDM/Canadian 2007-2008 Honda Fit, just got this to work with my car. Open the kick panel where the hood latch is and you’ll see a harness above it that you need to tap into. Wire your ground wires all to a ring connector and bolt it to the 10mm holding the hood latch. Wire unlock wire to white/blue wire on the car, wire lock wire to white/green wire on the car. For power, I used a fuse tap and tapped into fuse 28 (door lock).

[@paulkellner6462]

Is the white blue mostly blue with white stripe?

[@paulkellner6462]

Also, what which harness are these on? The grey one?

[@rumelmahmood1886]

Thanks for the video! Took me 5 mins to finish only due to your hard work.

[@khaliladnan9351]

Saying thank you is an understatement. Thank you ever so much. I just did my car jazz 2003 exactly the same but I used the plastic scotch wire splicer which worked great. Without your video and the fact I don't have a multimeter and don't know which is which I wouldn't have been able to do this job. Got tired towards the end and didn't bother about the indicators light :)

[@petkogeorgiev2103]

Thank you so much for this detailed and clear video! I was just able to add the same module (but from aliexpress) on my '03 Jazz. Fiddling with the tiny wires was a bit of a pain, but it worked out.

[@adammaloney6118]

Great video thanks. Same car but a bit newer (2007) so different fusebox and position of the cables and same unit (almost), this got me the confidence to install it. 👍

[@vjramgatie]

Dankjewel een hele mooie video 😉 perfect video

[@TerrySpringhamUKintel]

Thanks to your video this was an easy job for me. Thanks for sharing

[@gobinathmech8031]

Excellent demo

[@sydneyr9735]

Perfect video. Thanks

[@ballsack4321]

Nice install mate 👍

[@neknekmo4129]

You should show us how the meter reacted to the wire because i couldnt quite get mine right . I have a honda fit 2007

[@kuldeepsingh6306]

Sorry for the stupid question but in terms of connecting the wiring, and removing the insulation and putting it into the connector, should the old wiring be kept in? I'm struggling to remove the wires going into the connector in the first place (trying with pliers). I don't suppose you have any tips for that?

[@amp9438]

You could always try something like ScotchLok type connectors to tap into existing wires. I soldered as didn't have them. But to remove wires from the actual connector usually the pins have a clip which needs to be pushed down to release them from the connector housing. So a tiny screwdriver slid down side of the wire usual works to release them.

[@Dan-tb1ut]

Been fighting with all the diagrams for over a month with no resolve. Just found your video was thinking that this was not possible to do, but I can see you have figured it out. I can understand everything your talking about although I live in north America so the drivers side is reversed, but I want to know what is the deal with the black wire. Is that connected to the battery negative or frame ground? I know the 2x yellow wires are ground and im assuming the white wires are tapped into the wires coming from your main control switch on the door, Red is 12v+. Plus what should I do with the 2 orange wires. I see you have removed them. Any info would be a major advantage to my situation. Oh and my car is a 2007 honda fit. Thanks

[@amp9438]

The black wire and yellow ones go to battery neg or ground, doesn't matter I think. Orange wires weren't required so I removed them as the car uses a negative trigger.

[@gauchoking11]

Dan. I have the exact same car. Did you get it figured out?

[@Zephieish]

Can you wire the yellow (ground) wires to any ground or has to be in the CL loom?

[@amp9438]

Should be able to go to any I think

[@SM-od2jh]

Hi there , - how did you connect the wire ( tapped ) ? Did you strip the wires then tape them ? - did you use an wire tapping system ? - also I noticed you have taken a lot of the wires out form the module that were there when you opened the box and unpacked it which ones do I need to take it ? I appreciate help as I have a jazz and locks are packing up any other advice would be appreciated

[@amp9438]

Hi. I just stripped the insulation off the wires and soldered onto them. Didn't bother with wiring tapping as don't have the kit. Also removed the wires which weren't required from the module connector as weren't using those features. So just kept the power, gnd, lock, unlock and indicator wires

[@SM-od2jh]

A M P thanks buddy are you able to see my video I posted yesterday and point me in the right direction I’m stuck :( and also can’t remove the lower dashboard last

[@phutran5698]

Hi I did try and why we can’t wire up the module to door lock switch instead to lock and unlock wire signal?

[@efthivouloselia8127]

Hi. when you connect this system can you still use the key to lock/unlock the vehicle? or will it only lock/unlock the drivers door?

[@amp9438]

On my car everything still works as before so both key lock and inside door switch lock/unlock all the doors. Its important you tap into the existing wires but don't cut them so you don't disturb the existing connections

[@Mister_H]

You said the white wire with the blue stripe connects to the ground wires (yellow & yellow/black) going to the module. Do the yellow wires have to be connected to a connector like you did or can they just be connected to an earth? please excuse my lack of knowledge of earth/ground. Thank you.

[@amp9438]

Hi. Yes you can connect it to any of the wires which are ground or even the metal bodywork

[@Mister_H]

@@amp9438 Thank you. I am still stumped trying to find the lock/unlock wire on a Maza MX-5 but I am determined to find them...

[@TheSnoopdog14]

why did u choose the blue connector below the fuse box for power and ground ? i think u showed before on the video , that there's power and ground in the white connector on the door ( where the unlock and locking wires are essentially ) , so why u needed to find this blue connector for ground and power ?

[@amp9438]

From what I remember I needed a permanent 12v for the module so took it based on a suitable fuse, i.e. the central locking one. You probably can use another permanent 12v if you can find one.

[@lorenzoleonor990]

hey mate can you help me? i have a honda fit 2005 but i have different wire colors and placement on the harness

[@whoisme678]

Could you not have put the negative to the bodywork? I found if you use a safety pin with the little loop at end, you can use it as a temp probe and just push into the sockets and then decide whether it's right or not...then splice into the wires if all OK.? All negative connections go from battery to body. ?

[@amp9438]

Yes that will probably work. I chose to use the wiring in case there were any issue with the grounding to the car body, i.e. higher resistance etc.

[@iamkenlau]

Thank you for sharing this information, i have the same car as you but i dont know if its convenient to meet up and teach me how to install, im afraid that ill break something

[@amp9438]

Hi. Probably easier to find a local auto electrician to fit it if you're not confident. Shouldn't take more than an hour if they know what to do.

[@iamkenlau]

@@amp9438 Hello, thank you for this tip, but i don't know any good local auto electricians or websites for this, can you recommend a few?

[@shahinrashed]

Do both the yellow wires from the module connect to the one blue and white wire? You don’t show the clear connections in the video.

[@amp9438]

Yes on this module the 2 yellow wires go to negative so I connected them both to the white & blue wire on the door connector as that wire seemed to be connected to negative/ground.

[@shahinrashed]

Thanks very much. Very grateful for your help.

[@chrisshannon5542]

When you connect the Yellow and the White wires to the back of the connector, what stops these wires falling out ?

[@amp9438]

I stripped the insulation off the original wires making sure not to cut them and just soldered onto them

[@davapostance429]

Do you have any advice on fitting this to a 2005 jazz as the fuse board Is different to the one in your video thanks

[@amp9438]

Sorry don't know about 2005 model. The Honda forums probably have some wiring diagrams available. Also a multimeter is very handy for testing connectors etc.

[@davapostance429]

A M P no probs thanks for the reply

[@davapostance429]

A M P are the fobs already paired to the unit cheers

[@amp9438]

Yes but if not there's a button on the main module to pair it

[@missakhaladjian]

Why is the signal wires come in pairs?

[@fp274]

do these things last

[@suryadinugroho7094]

I cant manually lock the door, but it can lock by remote only after follow the installation in the video?

[@amp9438]

Hi. Yes the key locks on my doors started to get stuck meaning sometimes I couldn't get into the car. This was a big reason for me to install this.

[@giannisgiannis83]

my friend i have a corsa d 2007 i can do the same login

[@joeke3141]

But with these kind oflocking kits there is a chance someone else could open it right?

[@amp9438]

Possibly don't know how random the codes are

[@souravde970]

I have installed this universal central lock to my car which came with oem central locking but not workin g now. I have plugged the wire like you did and everything is working fine expect my driver door is not unlocking but all doors are locking and unlocking. What should I do? Can I contact you by email,

[@amp9438]

Does the driver door lock/unlock using the switch inside on the door? Also does the central locking work using the key in the drivers door? If not could suggest the wiring it broken between the door and the original central locking unit. I'd use a multimeter to test the wires, connections etc

[@souravde970]

@@amp9438 i will make video and share it with you

[@royburns7496]

is it ok to splice the wiring with a male and female bullet fitting

[@amp9438]

Don't see why not providing there is a good connection on the wires

[@iliyantoshkov9537]

Scheme ia not working on 2007 with a lil bit diferent fuse box , device can only lock, but not to unlock the doors. When unlock signal for unlocking remain on +12v.

[@saintadjg]

did you find a resolution

[@saintadjg]

I had same problem. connected the grounds directly to the car body and all works fine.

[@tomoslawrence]

@@saintadjg Looking to do this on a 2007 model, with a different fuse box than in the video. What did you use for the 12v source in the end? Thanks

[@saintadjg]

@@tomoslawrence I just found one in fuse box that had a permanent 12v feed and connected onto it.cant remember which one. if I get a chance lol take a pic. but just use a voltmeter to find a live feed.

[@ancientdiscoverys]

My mechanic told me he needs the car for about 4 hours to install this for me is that right ?

[@amp9438]

It took me a couple of hours, most of the time was spent figuring out the wires.

[@ivanmunoz4484]

Will this product work with a car that uses a clutch ?

[@amp9438]

Don't see why not. You just need a car which already has central locking but no remote control fitted

[@qasimali1543]

Hi mate…. I had try this but I can’t fix in my honda jazz.. can you do this in my car..I’ll pay you for this

[@amp9438]

hi sorry don't do installs

[@Wowzers15]

Does your original key not have buttons

[@amp9438]

No think it was optional extra

[@zedizdead]

My jazz 2003 gd doesn't have a lock/unlock button on the inside of the door (expect for the plastic pin). I can only lock/unlock using my door key or via the plastic pin on the inside. I was wondering if a alike kit would still work or do i need to get actuators?

[@amp9438]

If the drivers door lock opens all the doors at same time then it has the actuators and should work.

[@zedizdead]

@@amp9438 thanks for your reply

[@zedizdead]

Turns out that I need to get an actuator for the driver's door

[@user-km5jt8zu4e]

What if the locks input signal is positive?

[@amp9438]

The wiring to the module would be different. The instructions that come with the kit describe how to connect it if the signal is positive.

[@istvannagy4008]

Can you lock your car if the engine is running?

[@amp9438]

Yes

[@johnyp2967]

How would this work with a mechanical lock?

[@amp9438]

You need a car which already has central locking just no remote. There is another version which comes with actuators for each door but don't know if it's possible to fit these.

[@alkabirxybakil1284]

How to locate the 2 wires for lock and unlock?

[@amp9438]

When I installed this I used a multimeter to probe the connector and saw 12v on the wires when I pressed the lock and unlock buttons. I mean it went from 0 to 12v momentarily when the buttons are pressed. Alternatively you can probably find the wiring diagrams for your particular model. Usually they provide the colour of the relevant wires.

[@brucemclaren-]

didn't honda fits come with central locking?

[@amp9438]

In the UK I think the remote central locking was optional

[@kehindeabolarinwa6946]

Okay

[@jasonsmith902]

Why can't the system just plug into the cigarette lighter and trigger the central locking button

[@amp9438]

Cigarette lighter only has power when ignition is on so it wouldn't work. It needs a permanent 12v feed.

[@jasonsmith902]

@@amp9438 Brilliant, thanks
