well. why have only just one fob>?
the fobs die at 10 years old easy.
the buttons inside ,mine failed now 2times.
2015 to now. mine.
the buttons have switches in mine, gold plated
and the gold now looks like shot gun blasted. (under a microscope)
as in END OF LIFE worn out. all fobs do that.
or battery new is bad or battery in backwards
or battery clips bent or rusty
never have only one fob. (or land here x)

Check for a bad switch in the door.
Water leaking from the rag top-door seal joint often drains into the switch, causing a short or bad contact eventually.

I had a problem where my key fob did not lock or unlock the car, Renault Clio Dynamique, but the central locking button in the car did still work and engine turned over fine. Changed the key fob battery still nothing. Read online about disconnecting and reconnecting the car battery, (negative only) and hey presto it worked! All working fine now!

where can i buy a chrysler neon 1998 fobs?

First thing first-change battery in fob-most jewelers can do this as well as dealers-takes more power to unlock than lock

you will need to reprogram system

IF YOU TYPE 1999 RENAULT LAGUNA REPROGRAMME KEY INTO A GOOGLE SEARCH, YOU WILL BE ABLE TO PRINTOFF INSTRUCTIONS TO REPROGRAMME THE KEY TO THE KEY READER.THE IGNITION NEEDS TO BE OFF TO DO THIS

will your passenger door open with the key and is it just one side that your windows are not working or both. if its just one side it might be your regulator motor in the door thats not working if its both it might be your central locking pump usually in the boot. however if both of them are working fine it could be that your key needs reprogrammed however i think the 1st 2 are more likely to be the problem.

if you hav a remote control key &yr car wont respond . change key batrrey &contact dealer if still dont work for software
