Keyless Entry Transmitter: Technical Service Bulletins
Keyless Entry - Remote Transmitter Service Tip
Keyless Entry Remote Inoperative
Inspections of returned Keyless Entry Remotes for inoperative complaints found that many are due to oxidation on the contacts. Merely moving the
battery itself disturbs this oxidation and the remotes then operate normally. This would be a very inexpensive first thing to check for an inoperative
complaint. Check the battery and terminal condition and buff with a coarse cloth if either the battery or terminals are oxidized.
