2015 Chevrolet Equinox Key Fob Programming Guide

Quick reference

Step-by-step on-board programming

The 2015 Chevrolet Equinox can be programmed on-board, meaning you can do it yourself without special tools or a trip to the dealership. This procedure will program all of your remotes to the vehicle, so make sure you have all existing and new remotes with you before starting.

1. Close all vehicle doors.
2. Insert the existing, working key into the ignition.
3. Turn the ignition to the "ON" position (do not start the engine).
4. Press and hold the "UNLOCK" button on the working remote for approximately 15 seconds. While holding "UNLOCK," turn the ignition to the "OFF" position, then back to "ON" (do not start the engine). Continue holding the "UNLOCK" button until the door locks cycle (lock then unlock).
5. Release the "UNLOCK" button.
6. For any additional remotes (including new ones): Press and hold the "UNLOCK" and "LOCK" buttons simultaneously for approximately 3 seconds until the door locks cycle.
7. Turn the ignition to the "OFF" position and remove the key. Test all remotes.

Battery replacement

1. Locate the small release button on the side of the key fob. Press it to release the integrated key blade, and pull the blade out.
2. With the key blade removed, you'll see a small slot or indentation along the seam where the two halves of the fob meet. Use a small flat-head screwdriver or a coin to carefully pry open the two halves of the fob.
3. Gently separate the two halves. You'll see the circuit board and the CR2032 coin cell battery.
4. Note the orientation of the battery (positive (+) side up). Carefully pry out the old battery.
5. Insert the new CR2032 battery with the positive (+) side facing up.
6. Align the two halves of the key fob and snap them back together until they are securely closed.
7. Reinsert the key blade.

Where to buy a replacement fob

• Chevy Dealership: While you're guaranteed to get an OEM part, expect to pay a premium. A new key fob from a dealer can range from $150 to $300, plus any charges for key cutting and, if needed, programming. They will also program the immobilizer transponder if you have a new, unprogrammed key.
• Automotive Locksmith: Locksmiths often offer a balance of quality and affordability. They can provide OEM or high-quality aftermarket fobs, cut the integrated key blade, and program both the remote and the immobilizer transponder. Costs typically range from $75 to $200 for parts and labor.
• Online Retailers (e.g., Amazon, eBay): You can often find unprogrammed OEM or aftermarket fobs for much less, sometimes as low as $20-$50. However, you'll need to verify compatibility (matching FCC ID and part number) and then arrange for key cutting and programming separately. Be wary of extremely cheap fobs, as quality can vary.

If on-board programming isn't supported

The 2015 Chevrolet Equinox does support on-board programming for the remote functions, as outlined in the steps above. However, if you're replacing a lost or damaged key that has an integrated transponder chip (which the Equinox uses for its immobilizer system), programming the transponder will require specialized diagnostic equipment. This means you'll need to visit a dealership or an automotive locksmith.

Immobilizer Transponder: The 2015 Equinox uses a built-in transponder chip (often part of the key blade assembly) that communicates with the vehicle's immobilizer system. This system prevents the car from starting if an unprogrammed key is used, even if the key blade cuts correctly. If you get a new key fob that includes an uncut key blade, you will need to:

1. Have the key blade mechanically cut to match your vehicle's ignition.
2. Have the transponder chip in the new key programmed to your vehicle's immobilizer system using a scan tool. This procedure is separate from the remote keyless entry programming.

Cost Expectations for Transponder Programming: Expect to pay $50-$150 for transponder programming at a dealership or locksmith, in addition to the cost of the key fob and key cutting.
