The car does not detect the key fob after it gets wet.
Why does the vehicle stop recognizing the wet key?
When a key fob gets wet, the vehicle may stop recognizing it even though it still works to open the doors. This happens because the ignition system relies on an internal chip, which can be affected by moisture or corrosion.
• The car unlocks but won't start
• Transponder chip failures
• Internal signal problems
• May require rescheduling
• Possible replacement for the fob
Difference between opening and turning on
The opening and ignition systems operate independently, so one can fail while the other continues to operate.
Opening system
It works using a basic remote signal that allows doors to be opened without fully validating the key.
Ignition system
It depends on the transponder chip that must be recognized by the vehicle to allow it to start.
Why does it open but not turn on?
Because the ignition system uses a different chip than the opening system.
Can it be reprogrammed?
Yes, if the chip is not damaged.
