If just the lock cylinder, then a relearn is not necessary.....if BOTH, then it is needed...
Is it possible the bulb has burned out? When you just turn the key to "on"(not crank), that SECURITY light should come on.....
Keys have nothing to do with the system, they are blank keys for just unlocking the cylinder so it can be rotated......
So are you saying with the new cylinder, the SECURITY light does not come on and the car starts?
I replaced the ignition lock cylinder which comes with a NEW passlock
sensor the cars body control module won't recognize
the new lock unless I reprogam it. The car shouldn
start unless I do the the relearn process.
As for the keys since they are different
wouldn't the passlock sensor send a different code because it'* a new lock to the cars body control module?
came on when I reconnected the battery cable. Since the light never came on the point I'm trying to make is the car shouldn't have started
without doing the relearn process but it did
. Remember the car started without
doing the relearn process but I still did the relearn process even though the security light wasn't visible.
