My Chverolet Blazer has this immobiliser problem and the only people that i know that are able to do EU spec cars are based in Manchester England. It is not possible to programe new remotes to the EU cars. VERY VERY VERY expensive fault. I feel for anyone that has a Blazer with this fault.

 

I have, or rather my partner has

 

There seems to be two threads going with this same problem, I have answered the other one, My UK cruiser will go through the above procedure with the original fob, but not with a fob I bought which has the same part number. has it ever worked? open the fob check the contacts to the battery, I had to re solder a loose connection to the circuit board. Don't be tempted to buy a USA fob, it probably won't work. The receiver for the signal from the fob is to the left of the glove box, drop down the glove box and you should see it, has a long black wire that goes round the passenger door opening, might be worth checking the contacts on the box, mine has another box attached to it, not sure if that is the imobiliser or the CPU.

 

Make sure the doors of the vehicle are closed when you are doing this. All of them. Even the hood. If the security light flashes, it is not going into the proper mode. If when you let go of the unlock button, the doors don't lock/unlock, it is NOT in the mode, and will NOT accept new pairings of remotes.

 

The key fob is programed as per other post,s: however the UK Blazers have a dual anti theft system that only Bauer Millet can overcome properly. It is costly procedure but they (Bauer Millet) are very good and your car will be perfect when it comes back. My Blazer workss fine since the repair was done. I hope this helps.

 

Sorry but do you mean they fix the system or remove it completely? Might be how I read it but not sure.
