Electronic immobiliser ignition key

The electronic immobiliser device locks the engine management system as soon as the key is removed from the ignition.

All keys contain an electronic component [transponder chip, see picture below] which ensures that only your key can start your vehicle.

If the electronic immobiliser device does not recognise the key once it has been inserted into the ignition, then it will be impossible to start the vehice.

CODED Card

A confidential card is given to the new owner when he takes delivery of his new vehicle.

The card bears a hidden access code for the use of the Citroen dealer when maintaining the electronic immobiliser device.

Advice

Make a note of the key numbers and the remote control number. Keep the card in a safe place – not in the vehicle.

Keep the coded card bearing the immobiliser access code in a safe place (never in the vehicle).

If any key modifications become necessary (addition, cancellation or replacement of a key), you must take the confidential card together with all keys to a Citroen dealer.

Changing the remote control battery

Pop open the case to the keyfob to gain access to the battery: CR 1620 (3V) button cell and replace the battery.

The remote control must be reinitialised after changing the battery. To do this, use the key to unlock the doors and within 30 seconds press button A [LOCK] on the remote control twice.

Getting a New Key

If you go to a Citroen dealer you will need:
- Registration Document (V5)
- Proof of identity (photocard)
- Proof of address that must match address on the Registration Document
- The key number (see picture below)

What can I do if I don’t have a key number?
You can have your Citroen dealer email Citroen to do a key search from your VIN number on the Registration Document. I was told this costs £15.

Programming a New Key

Once the key has been cut either using the key number or another key as a guide then the immobiliser device needs to be programmed via the ECU to recognise the transponder in the key (see picture). This is where the code on the coded card is needed to gain access to the ECU.

How much does it cost?

I had the key number and Citroen quoted:

£34.33 for replacement key (+£15 without key number)
£69.50 for a replacement remote control keyfob
£46.58 for half an hour of labour for programming

Are there other options?

Yes. Auto locksmiths claim to be able to help to replace keys, programme transponder keys, fix or replace broken keys and to help with lost keys or lockout situations. Do a Google Search. Some folks have used Timpsons with success.

Visited Timpsons. Timpsons have many stores and claim to have expertise in cutting transponder keys. They try to read the transponder in your existing key and copy it, then they write that code to a new key that they cut for you. They claim to be able to copy Saxo keys and prices start at £30.

Pictures:

1. Transponder key with remote control keyfob
2. Transponder key slot
3. Plastic label with key number highlighted in blue; the other numbers may be for the remote control keyfob
4. Citroen coded card

IF you get a key cut without a transponder, then this key will be able to open the doors, petrol cap but will not start the car.

If you change the ignition barrel then the key key must be programmed into the immobiliser via the ECU.

A replacement remote control keyfob can be purchased if your fob is physically broken or a plastic button is broken. The inside of the broken remote can be transplanted into the new case.

£135 to have mine cut and programmed by a locksmith, but part of the charge was for travelling, ie bout 35 miles.

Agent_Orange · 9th May 2009, 18:34

Good guide there mate.

I got some mad key problems: The key don't work in boot or drivers door, but does petrol cap passenger door and ignition?!

Somehow and I say somehow cos this never happens to normal people.... My Dad broke the key off in their 307 door-lock. RAC came out with new lock kit and did it all for nowt!?!?!? Nice

That just saved me from getting very annoyed haha! Spent ages trying to get the fob to work after replacing the battery, worked straight away after I "reinitialised" it.

Thanks a lot mate.

or go to timpsons key cutters and theys cut n code your key for £35 quid. thats for the mk2 keys the kinda cross ones. cheaper than citroen

chinkostu · 17th May 2009, 12:15

when i needed a new key cutting for my punto i just went to timpsons. they cloned the transponder chip onto a new key, and then cut the key

£35 it cost me, would imagine it'd work with a saxo's key aswell. of course you don't get a original key back, but who the hell cares? looks the same and does the job!

Probably a fob thats not for the car. Have you tried doing this?

Hi. Everyone

My remote didn't work since last week (it worked normally before)

And i changed the battery, CR1620 3V for sure.

I tried what mentioned here to re-initialised my clipper, and it still doesn't work

Anyone succeed with this way ? Or i did sth wrong?

Thx a lot.
