How do I get this replacement key cut and programmed?

Programming depends on your vehicle: some trucks support owner self-programming, while others require dealership or locksmith programming to pair the immobilizer chip and remote functions.

• Uncut blade must be cut by a locksmith or dealership
• Follow packaging instructions for self-programming if available
• If self-programming isn’t supported, use a professional to pair the chip
• Ensure remote testing after programming for lock, unlock, and panic
