How do you program remote for Peugeot expert?

To program a remote for a Peugeot Expert, first, ensure that you have the vehicle's key and the new remote. Insert the original key into the ignition and turn it to the "On" position without starting the engine. Within 10 seconds, press and hold the lock button on the new remote for a few seconds, then turn the key back to the "Off" position. This should sync the remote with the vehicle; you may need to repeat the process if it doesn't work initially.
