I have one of those remote wireless units on my keychain with three buttons. The three buttons will lock or unlock the doors and sound the truck horn for an alarm. I have a 1999 Ford F-150. The remote unit does not work all the time. I think it works better when the temperature is cool but I have had it not work at all during cool temperatures. I replaced the batteries a short time ago so I do not think it is the batteries. Does anybody have any clues on what to check for or why this might be happening?

Thanks in advance.

This might sound strange, but I read it in a few posts.

Try holding the remote under your chin, and see if the distance increases. This seems to be a case of using your body as an attena, and might show if you have a weak signal.

Do you still have the other remote ( from factory with 2 ) to try and see if the same problem happens ?

Just trying to desipher ( maybe ) if it is a remote problem or a problem with the rcvr in the truck.

Let us know.

 

Yes, I have 2 remotes. In the past, it seems that if one does not work then the other will not work either. I put new batteries in both remotes not too long ago so I will try both of them if the one starts failing again. I will also try the "under the chin" thing if the remote stops working also.

Thanks for the post!
