Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
First make sure your battery is fully charged and try it again a low battery can cause an issue picking up the signal. Otherwise a key learn programing procedure will need to be performed in order too see if there is a communication error, sadly this can only be done by a dealer via TIS2 web. does your remote start work?
sorry I am at work at the dealer so I check post about every 30 min, I would deffinately start by either getting a boost charger or jumper cables on it.
If it is a small charger it will likely need a bit, the jumper cables will charge it faster but if you have a bit a regular charger will charge the battery more.
Awesome, yah i would keep it running for 45min at least glad you got it! before you manually charge it make sure it restarts from the car having charged itself, that will verify the charging system is all in order.
