To activate the key, press the PANIC and lock buttons simultaneously. A beeping light on the PANIC button shows that the key is active now. Then put in your old key.

The new key box contains a programming device. If there isn’t, then you’ll have to buy one yourself. The device can only be used on one Jeep Gladiator. 

Read the manual and follow the instructions to switch the dial for your Jeep Gladiator model. 

Park the car and make sure the engine is turned off. Switch on the hazard lights. Connect the device with the OBD, after which you will hear three beeps. 

After hearing the beeps the second time, turn the engine off and pull out the key. Insert the new key and turn it on. 

Step 5: Press the top button on the programming device. 

On top of the programming device, you will see a button. Press it and wait 10 seconds until you hear a beeping sound. Pull out the new key and press the button again. 

You’ll hear the beeping sound, indicating that your Jeep Gladiator key fob has paired successfully. Now you can test the lock and unlock the buttons.
