How to Program a 2020 Chevrolet Suburban Ignition Smart Chip Key Transponder

Step by Step How to Programming Instructions:

If you find yourself with one or no keys for this vehicle, note that it’s not programmable onboard and requires a qualified professional to program the ignition key. Follow these steps:

1. Find an automotive locksmith in your area by visiting LocateALocksmith.com.
2. If your vehicle is still operational, consider driving to the locksmith instead of having them come to you to save money.
3. The locksmith will then connect specialized computer equipment to your vehicle to program the ignition transponder chip key. Use these instructions to program the key.

Note:
You are given 2 keys, but you can add up to 6 more keys. Customer key programming (except for vehicles sold in Canada) can be done if you have two valid (already registered) keys and blank (not registered) immobilizer keys specially cut for your vehicle:

1. Insert the first programmed key into the ignition and turn it to the “ON” position for 5 seconds.
2. Turn the ignition to the “LOCK” position and remove the first key.
3. Within 30 seconds of turning the first key to the “LOCK” position, insert the second programmed key into the ignition and turn it to the “ON” position. About 10 seconds later, the immobilizer indicator on the dashboard will start blinking.
4. When the immobilizer indicator starts blinking, turn the second valid key to the “LOCK” position and remove it. Within 30 seconds after doing so, insert a blank cut key into the ignition and turn it to the “ON” position. Perform this operation no more than 30 seconds after the immobilizer indicator starts blinking. When the registration of the ID code is complete, the immobilizer indicator will come on for 3 seconds then go off. If an error occurs, the immobilizer indicator will go off during the procedure.
5. If you wish to program another key, repeat the process from step 1.

Use these instructions to program the remote:

1. Locate the Data Port.
2. Insert keys in ignition and leave in the OFF position.
3. Ensure there are metal contact pins in terminals 1 and 4 and connect the Data Port with a suitable jumper wire, leaving the jumper wire connected throughout the programming procedure. Make sure you know which terminals are 1 and 4.
4. Within 10 seconds after connecting the jumper wire, press the Hazard Switch 6 times. Note: The doors will automatically lock and unlock once at this time, indicating that the system is in the programming mode.
5. Press the LOCK button on the remote to be registered three times within 10 seconds. Upon successful programming, the door will lock and unlock once.
6. Repeat step 5 with up to 4 remotes (including any existing remotes) within one minute. After completing each programming, the doors will lock and unlock once.
7. Disconnect the programming wire and remove the keys from the ignition.
