Programming new key fob

Recommended Posts

Hello All, First time ask on here so please be patient!

I have tried to buy a new key fob for my 1995 E34 525i from Sytner leicester, They tell me that whilst they can supply the part they are unable to program it! I have been told by a long time BMW Fitter that this fob needs links soldering across certain areas of the pcb.

Does anyone have the details of what is needed or do I give up on remote locking/alarm etc?

Thanks in advance

I'd ask my local dealer 1st because in my Bentley's manual it has a series of steps which tell you how to sinc the fob to the car, it doesn't mention anything about soldering.

For my new remote key that I bought from BMW a few years back, I just followed the instructions in the original handbook that came with the car!  I have a feeling the ignition had to be in and the button on the key held in

The answer to your question will depend on which type of system you have installed in your car.  Some of these fobs are NLA.

 

Have a look HERE in the first instance - it's as good a guide as I've seen.

two types - one has solder links and you can copy the original one you have (looks rectangular shape with corner cut off), the other type needs programming.  Syncing to the door locks I think can be done but the alarm/immobilizer is the bit that is tricky if it needs coding.  Second hand fobs can be bought off ebay and the one pictured below is also used in some older Subaru models too.  I found a local independent BMW specialist who could program the fob when I had to get one a few years back.

 

this type needs special programming:

The type above is a sigma AC38 and you can find these and the AC110 on ebay which work.

 

There is a programmer which i had that i used to code these to the 3g alarm (i did it on my e36 M3)

 

At the time my local car alarm/ hifi shop reckoned they could code the fob.

 

The programmer was sold on here to (i think) Azmontana - he may well still have it?
