Multiple beeps unlobking door: battery or what?

Multiple beeps unlocking door: battery or what?

I can't recall seeing this one mentioned, and a search doesn't bring it up recently.

Two times in two days, unlocking my door has started a series of the unlock beeps, maybe 5-10 repeats while I get in the car. Not sure starting the car is why they stop, but they do stop.

Weak battery? Gremlins?...

 

In light of the fact that when I went back to my car a little bit ago to get some soda I forgot and it did the 5-beep-sequence (counted this time) twice while standing at the car (unlocked, locked, unlocked again), we can eliminate the alarm-trip thing unless that's broken.

Other than being annoying, it's not worth fixing unless it's one of those Early Warning things that says I should get a new battery ASAP. Google doesn't bring back any post but mine on this issue, at least using the kind of problem description I stated...

I'm going to open and slam all the doors just to see if that helps...

 

The door-slam idea worked.

When I went home from work, I unlocked the driver's door which normally unlocks all doors and I got the 5-beep thing. I then started slamming all the doors, working my way around to the front passenger's door. It was still locked, and touching that sensor unlocked it. So I slammed it then locked the doors again with that button. When I got back to the driver's side everything unlocked with no more issues.

I guess there's a reason for every error code, even if you don't know you are hearing one at first...

 

My beeping came back, and slamming the doors didn't help this time.

Again, the passenger door didn't unlock with the others, so I stood there and unlocked/locked it with the black button several times then the issue cleared up again. I've unlocked the driver's door twice now with no extra beeping.

Now it's a waiting game for it to come back again. Meanwhile I guess that passenger's door needs more exercise or something...

 

Here's an additional piece of info. I have a thread about my front passenger door lock not locking electrically anymore, and while it failed to lock I got the extra beeps. Starting Friday night, after locking it by hand for several days, it started working normally again and there are no beeps.

So it appears that if something makes the lock mechanism sticky, like dirt or paint or whatever, the lock needs to be cleaned to avoid malfunctioning and beeping. Slamming seems to help, although I'm not sure why manually locking helped when electric unlocking still worked.

Of course, this could just be the last few times the lock mechanism works at all and Tuesday it could die completely. Fun stuff to think about...
