Won't start, security light blinks for 10 minutes
\015 When I try to start, it won't fire up and the security light blinks. It blink's for 10 minutes and then I try to start again. No luck.\015
There is a computer chip in the lock cylinder that goes bad ,so change the key and cylinder,then leave new key on until the light stops flashing about ten minutes this will set your new key to the security system hope this helps
