Mercury Mountaineer Key Fob

cwollercwoller Member Posts: 1
Recently I was trying to program an new FOB to work with my 2002 Mountaineer. The programming did not work and the one FOB that was working no longer works. I went to a locksmith and he tested the FOBs and they are transmitting a signal. He wasn't able to get it working either. I really don't want to go to the Ford dealer to fix this cause I know I will be charged significantly to repair it. Any ideas?

    Disconnect the negative cable from the battery for a a minute, then reconnect; this should clear it up to a point where you should be able to program a good remote following the standard sequence, lock door, switch key from off to run 8x, then press any key on remote or remotes within 20 sec. good luck...
