well,well, there are separate relays for lock/unlock and the body control module gets involved. its messy. need to get a good look at the door wiring schematic. actually two unlock relays,one for driver,one for all the rest. they all lock together, but unlock separatly.


you can check transmit on the tester at autozone/probably any auto parts store.
ltr:
I cant find it but It seems like the bcm is where the actual remote signal goes first. but I think the problem is in the door logic module. needs resetting. maybe play with the connectors as has been discussed somewhere here. its unlikely both unlock relays went bad.


you really should confirm that the mote actually transmits on unlock.
I have a small frequency meter and it shows activity on lock/unlock. just tried!

 

Not sure what you have? Can you upload a pic of it? Did you try and clean your OE remote & install a new battery?

After you replace the battery you have to repeatedly hit lock and unlock until the remote starts working again.. GL

 

I've order the part that you shared just 30 minutes before your post :-)
Monday it will come and I will clean the small PCB and will reuse it with the new housing.

But could you advice me what is this defice on the picture (key remote contro and ??????)

Sorry for so many posts did not find a way to edit post. Could someone tell me what is the silver ring-ish thing on my keys? Looks like some kind of device? Never had similar.

 

a guess, this is only a guess, it looks e it could be, A PART of a key chain flashlight !, the battery end of it. it looks like 2 button batteries.
do they come out? if so, the rest is missing. toss it if this is so.


a guess.

 

Like -3 stated, looks like part of a keychain flashlight..

By the looks of your unlock button on the keyfob(worn), You definitely need new pad/case. GL
