Hi Guys

When I bought my Stilo 5 years ago I only got one key from the dealer (the spare key) as the previous owner had lost the others. It has always bothered me only having one key, and not having a remote controlled central locking system. I pretty sure my Stilo has remote central locking as it has all other available upgrades.

Now I have been offered a complete locking system from a scrapped Stilo incl. 3 keys, (2 of them with remote) the key code papers, 3 locks and one ignition lock. To me it looks like the complete set.

My question; is this an operation I can do myself, or do I need FIAT to re-programmer the car for the new Keys? Changing the locks should be relatively easy, but I have no idea about the electronic issues I could encounter, i.g. changing the immobilizer to the new keys.

Does someone have any experience?

Remote side of things you can do you're self with the code and MES software, the immobilizer might be an issue though - although can be sorted if you get the engine ECU and body computer from the donor vehicle also I believe.

Ok, thanks. That is more or less what i expected, however changing ECU and body computer is not really anything i enjoy doing.

Im still curious if the keys are locked to the immobilizer, or if it can be reprogrammed?

your transponders belong to the bodycomputer and can't be reprogrammed again - the ecu can be virginised to relearn new immo data when it is changed so that's not a problem.
A good locksmith can make a new working transponder by using the data from your current bodycomputer - the new transponder can be fitted in a normal or remote key which then can be programmed to your car.
