Probably sounds like a daft question..car hasn't moved in a while, after a flat battery it no longer accepts the key '' Key not accepted'' at a complete loss as nothing has changed in two months other than the flat battery, any help would be appreciated...............thanks

did you try to jump start it..what about the spare does it do they same..either rfid chip in fob has failed or the ism has gone..

No, just charged the battery and replaced it...it didn't come with a second key, just seems strange a flat battery on the car has lead to this, the key was just left on the side as it has for a year or so now.

Did you insert key(fob) to ISM and turned ignition to ON?

the ism contains electronics,it's possible when you reconnected battery something went pop..try another ism and report back..no need for tech2 to replace ism..
