Are you the original owner? Have you ever replaced your fobs, themselves (not talking about the coin batteries)?

 

Yes I am the original owner and they are original fobs. We're planning to replace the one that is confirmed dead.

 

there was another post with almost same key problem ?

they were missing a linkage part in the lock so key did not work

I went out after reading that and tested mine and then wondered where the heck is the key hole on the other doors

 

Thanks Cord, I remember reading the other post re: the linkage - so that is what I will have somebody look at. Happy travels.

 

My fob that I have been using for 6 years decided not to work a week ago. I had been having an on-going intermittency that had required my whacking it once or twice to get it to work. This time, no amount of cleaning of the contacts or bending of the contacts as a poster suggested a while ago would bring the fob back to life. As a last resort, I even put in a new battery to no avail.

I have a small bottle of what a tech called "tweek" that I got from him at work about 25 years ago . The liquid can be applied to electrical contacts and will cause them to conduct again. I applied "tweek" to the battery contacts of the fob and the fob began to work again.

My thought is that the electronics of these failing fobs haven't gone bad (unless they have gone through the wash or been for a swim in the ocean), but that the battery contacts are at fault. I suggest cleaning the contacts as best that you can before resorting to purchasing a new one.

 

We are only dealing with around 3 volts here which isn't very much and some devices are very susceptible to voltages so clean contacts, clean batteries and positive (enough) pressure is paramount. Anything below 3 volts will cause a problem as well.
