keys keep losing program
Have these keys been programed by a "locksmith" or are they the OEM factory keys... keys don't lose programming the Vehicle does and its NOT common. These are transponder (transmit and receive) keys Ford uses an ** bit unit, there are "remotes" which are separate from a KEY, and are programed and FOBS which can contain a laser cut key or flip out key as well as act as a proximity key, PUSH button start and unlock features in use the last 10 years. SO , the '12 Focus has a factory PATS system which will not allow a CRANK, rotation of Engine to START and run, when key is turned? Who said the Keys are losing / lost there programing the Ford dealer? do you have a remote that is functional? lock, unlock etc. Regards
I have an 2012 Focus and OEM key keeps getting a 'key not detected' alarm. A second key made by a Dealer works all the time. The problem key may or may not work. Changed the battery in it and same problem. Any ideas?
some aftermarket chips have a weak signal return, the car will reject as wrong key (theft mode) get oem key programed. try that first, the key your using is 80 bit that holds a lot of information if the signal is returned with anything corrupt it want work
