A Quick Question on Key Codes

[doctle]

I don't have a spare key for my 307. I don't have the little card with the code either and I'd like a flip key into the bargain. Are those ebay keys any use? Is there any way I can get the code? Thanks

Peugeot will be able to supply this as they do maintain the codes from a central database - whether they will provide this though may depend. They might provide you with the confidential code - but that is used by them to provide a replacement key / key with fob, but will need programming.

The ones on the bay are likely to be a copied fob shell, into which you can place your original key and transplant your fob circuitry chip and battery - but it won't work without the transponder chip from your old key fob. The non-fob keys have the transponder chip built into the black plastic moulded around the key.

Those spare fob cases are fine if you have the same type of fob and the flip mechanism has failed - you just transplant the lot over to the new shell. It can be a bit tricky getting the key blade in though.

Thanks Marc, I really want a spare key "just in case" I don't mind even the standard key just the flip key looks a little better.

No probs - just bear in mind that you won't be able to start the car with the key alone - the chip in either the fob type or the flat non-fob key is needed to start the car as there is a receiver aerial around the steering column / ignition area that detects the chip and sends this to the BSI and then to the injection ECU once the codes have been verified.

Here's a link to a video from 'C3 Owners' showing a conversion to the later flip type. It will be similar to your Peugeot.


I would also suggest you look at the following link (from the video) as it shows you where the immobiliser chip is located in the flat type:

My key has no remote buttons I think it must be a locksmith key the bloke I got the car off said he had mislaid the original rcl key

Unless it's a really old system (i.e. Citroen BX era) there is no need for a code, you just pair a new key with the car. The code is to get the physical key cut.

I remember there being some ritual to perform when I got a 2nd key for the first Xantia I had, turning the ignition on and locking / unlocking with the new key or somesuch. Presumably newer systems use a Lexia.

[GiveMeABreak]

Yes, but PP2000 for Peugeot. As I said in my first post the confidential code is to get the key ordered via the dealer.

Some confusion here...

There are 3 parts to modern keys - the physical 'key' bit, the immobiliser chip and the remote locking function.

The 'code' to get the key cut is a numerical representation of the physical shape, and required (possibly!) if you order a pre-cut key via the dealer - although a high street shop will just copy, and some online places can copy via a photo.

In order to get the key to start the key, you need to code the chip to the car - this is done with Diagbox, and requires the 4 digit code on the card that came with the car. The dealer will be able to recover this code if you don't have it (probably requiring his palm crossed with silver, and sight of the reg doc to show that you own said car).

The remote function can be activated once the key is coded to the car for the immobiliser, and can be done without Diagobox (although it will do this stage as you are coding the keys in). In theory I guess you could synch a separate remote to the car which had no key function and wouldn't actually be able to start it!

Note you cannot code a second hand key to the immobiliser if it has already been coded to another car without replacing the chip - it's a one shot operation.

I bought a key off e-bay for the C4 - not one of the very cheap ones, it was a UK made one I think. I had a bit of trouble getting it cut as shops were reluctant to do it, but I got it done in the end. Coding it to the car with diagbox was easy - but note you need all the keys you want to be active (even ones that are already coded) to hand, and go through the coding with each one.

If I were to get the Planet/diagbox software could I code the key myself? Im sure the software would be useful, scans are about €80.00 a pop in dealers here

Yes, but you will need the full Lexia kit (around £100, depending on where you go, but I would recommend Easy Diagnostics, as their equipment is good, and they will (with the code on the forum) give a discount) and the security code to allow access to the relevant menus (as well as a laptop running a 32bit version of Windows). You will need to do ALL of the keys at a session (otherwise any that are not done will be 'forgotten' by the system).

I've known people just tape the old keys base to the steering cowling and use a new non coded key.
I guess it depends where you live, how old the car is and how much you care.
Doesn't seem a bad idea to me though.
I think I'd take the cowling off and put the old key inside it if I did it that way.

I'm 1/3 Scottish could I take out the chip and tape it to the pickup?

[myglaren]

Only if you deep fry it first

[elma]

Probably.
I've never seen anyone take the chip out before. My mates have hacksawed the metal bit off and taped the whole plastic bit on.

[doctle]

How do I get the chip out? no pun intended
