Hi everyone,
I have a 2004 2.2 automatic Z4, i have an intermittent problem with locking (mostly not working but will occasionally)
So i bought the car as a dooer upper, it had no remote key with it, only the spare emergency standard key. I had a new generic key made and programmed which worked fine, that was about a year ago.
Ive started having trouble with unlocking (locking will always work on the key, the boot also works every time off the key) i have to put the key in the door to unlock it which will only unlock the driver door (passenger and storage compartments remain locked) so to unlock those i press the central locking button inside the car, this is also playing up, when sat in the car i can hear solenoids trying to do something.
My biggest concern is that with the key and interior button not working, i cant get out the car as when i try the door handle, it will lift the lock button but not open the door, as soon as i release the door handle, the button returns to locked position.
Car battery only a year old and fully charged, have also tried new battery in the fob. Any ideas gratefully received

Sounds like the GM5 module is playing up.

Lots of info if you search GM5 on this forum, but basically you need to check if you have a 5RD or a Star 12 Low. They are not exchangeable.
You can get a secondhand one and then pair your key to it, but you may need to code any settings you have as it will retain the ones from the donor car.
Or you can send yours off to be repaired.
Not everywhere does Star 12 so if you have one of those make sure you find the correct repairer. Lots on eBay.
Or possibly bigwinn can help you as I believe he recently invested in the soldering station and some relays.
