Step-by-step on-board programming
Programming a new key fob for your 2018 Chevrolet Silverado 1500 is a straightforward process that you can do yourself in just a few minutes. This procedure will work for the 4-button and 5-button key fobs. You will need to have all of the key fobs you wish to use with the vehicle, including any existing, working fobs.
- Insert the existing, programmed key into the ignition.
- Turn the key to the "ON" position without starting the engine.
- Turn the key to the "LOCK" position and remove the key.
- Within 5 seconds, insert the new, unprogrammed key into the ignition.
- Turn the key to the "ON" position without starting the engine. The driver information center (DIC) will display a message indicating that it is ready to program a new key.
- Hold down the "LOCK" and "UNLOCK" buttons on the new key fob simultaneously for approximately 15 seconds. The vehicle's horn will chirp, and the DIC will display a message confirming that the new key has been programmed.
- To program additional key fobs, repeat steps 4-6.
- When you have finished programming all of your key fobs, turn the ignition off and remove the key.
Battery replacement
The CR2032 battery in your key fob can be replaced by following these steps:
- Use a small, flat-head screwdriver to gently pry the two halves of the key fob apart.
- Remove the old battery and insert the new one, making sure that the positive side is facing up.
- Snap the two halves of the key fob back together.
Where to buy a replacement fob
- Dealer: The most expensive option, but you will be guaranteed to get a genuine OEM key fob that is compatible with your vehicle. Expect to pay around $150-$250 for the key fob and programming.
- Locksmith: A more affordable option than the dealer, and many locksmiths can also cut and program the key for you. Expect to pay around $100-$200 for the key fob and programming.
- Amazon: The most affordable option, but you will need to be careful to purchase a key fob that is compatible with your vehicle. Expect to pay around $20-$50 for the key fob. You will then need to program it yourself.
If on-board programming isn't supported
If for some reason the on-board programming procedure does not work for your vehicle, you will need to have it programmed by a dealer or locksmith. This is because the key fob contains a transponder chip that needs to be programmed to the vehicle's immobilizer system. The cost for this service is typically around $50-$100.
