Key Fob not locking/unlocking - actuator or GM5?
 
So, I had this issue once with my dad's e39. The key fob would not lock/unlock the doors. It was a fairly easy repair. I did it awhile ago so I don't remember the specifics, but the repair was done in the trunk.

The same issue is coming up on our e46 and based on the searching I've done, it's not as straightforward. It looks like it can be a problem with the actuator or the GM5 module. Both look like fairly involved DIY's. Is there a test I can do to determine which part might be the issue? I'm hoping to avoid an unnecessary DIY.

Thanks!

Scott may chime in soon?

I think a few questions would be:

1. Is the problem only with a single door?
2. Do the interior lights come on, but the door not unlock?
3. Do you have the problem also unlocking the car using the central locking button?
4. How intermittent is the problem and does it appear to be heat related?

my key just stopped working on all doors and trunk. the interior lights also do not turn on. Sometimes if i shake the key (i do not hear anything inside) and then press unlock it will work. I think its broken from being dropped. Should i get a new key?

does the central lock button work if say you try to get in and the windows are down.
does it seem to do it more in the hot day rather than the cool night?

No they don't and the temperature does not change the outcome. I was hoping all it needs is a new battery

yeah, doesnt sound like the GM5

Bad key. Get it repaired or buy a new one. It's up to you.

So the SAME issue is happening with your E46 which from what you wrote about the E39 problem I see that you are having issues "The key fob would not lock/unlock the doors." This is not a GM5 or actuator problem. Sounds more like a key fob, key sync or FZV antenna amplifier problem.

Make sure you call around to the dealers and ask for the key by part number.

Master key/keyfob part number - 66126955750 (BMW list price is showing $166.29 last I checked, some dealers will sell for as low as $124.72).
