When to Call a Professional
Call a professional locksmith or dealership if you need a new key programmed, the immobilizer module appears faulty, or you suspect the ECM needs reprogramming. Also seek help if you have no spare key and the current one fails.Frequently Asked Questions
Can I drive with error code P0513?
No. Error P0513 usually means the engine will not start or will stall shortly after starting. The immobilizer prevents the vehicle from being driven to protect against theft.
Will disconnecting the battery fix P0513?

How much does it cost to fix P0513?
Cost varies. A new key battery is cheap ($5-$10). A replacement key from a dealership can cost $100-$400. Immobilizer module replacement or reprogramming may cost $500-$1000.
Can a locksmith fix P0513?
Yes, many automotive locksmiths can program new keys and diagnose immobilizer issues for less than a dealership.
Is error P0513 related to the key battery?
Yes, a weak or dead key battery (in keyless entry systems) can cause the immobilizer to not read the key, triggering P0513.
