but the problem is, i can't close the car with the remote. Only with the key. And than the turn lights will not blink. When i disconnect the battery for the night. The next morning when i connected te battery again, every thing will work propperly. Event the remote works. Turn signals blink en the becm will go to sleep in seconds.
BUT, and now it come:
when i put the key in to start, without starting. When i than get out of the car and try to close the car with the remote, is't game over. Not the remote not the becm will go to sleep not will blinke the turn signals.
It's like there is a problem with the code in de remote and becm. One of the 2 is forgetting the wright code. Think i start with buying a new remote and see what it will bring.

or does someone has an better idee?

already thanks

BECM not going to sleep (or repeatedly waking) and draining the battery sounds like an RF issue. If you unplug the RF unit behind the drivers-side (RHD) rear parcel shelf the RF will still work but only when you put the key near the window.

If the remote won't lock the doors but the car starts fine etc then it sounds like the lock motors might have burnt out - common if getting RF interference.

Question: if you unlock or the doors when inside, do all the other doors lock OK (or unlock)? Same passenger and driver's side?
