    Have just replaced my battery (key fob) as it wasn't locking / unlocking / not boot opening either.

    Still have the 9 flashes.

    Is it likely to have become unsynced?
    If so how much is a starr reprogramming likely to be at a non merc garage? (£60 quote on the phone so far to "have a look at the fault codes & attempt a reprogramming via a local locksmith).

    CONTEXT: one key is fine, still operational so starting etc not a problem.

    Other key (faulty) I opened up, replaced battery, re-opened, checked the micro switches all "working" (they were)

    I "think" it got repeatedly pressed in my pocket if that gives any insight.

    Dust / dirt /detritus inside fob? ..was actually very clean (I also have it in a silicone cover for extra protection).

    Other faults to look for?

    Do you mean it can be dodgy towards one key but function perfectly with another?

    (or did I summise my problem badly)?

    Sorry, didnít see that key statement from you....

    If receiver is dodgy with one ,itíll be dodgy with both. If youíve lost synch on one key, itíll be confined to that one key, but both keys will need to be re-presented to the car, for the car to re-learn them again.

    so in your case itís the key at fault - or the car has lost itís way with that key.

    Thanks, for the verification.

    Shall I just buy an OBD key reprogramming unit & be done with it!? ...I have an a class I need to see if it's done the same thing too!I
    If so, any recommendations, I note some run on "tokens" / others it's an ongoing yearly license for star units etc.
