Key Fob

[donsmrs]

Wife’s 2015.
Key fob keeps refusing to lock or unlock car. I fix it using the 8 times on/off method but next day it’s back not working. Keypad on door works fine.
Any ideas?
Thanks.

Every time it happened to mine, 2000, 2007 and 2014, the only real fix was a new key fob. I got mine from a locksmith, not from the Ford dealer which may be why I never had to replace the new fobs. Cheaper, too.

All key fobs have to be reprogrammed at the same time. I have three key fobs. If not, then the key fob that is absent from the process will no longer work.
