I would give Tracker a ring and make sure of the correct way to do it as it will be paired to the alarm, just like your ignition key is paired for your car, with a car one you only have a short period of time to do it other wise it can loose the pairing ( did it with my truck a few years ago π³ ) by having the battery out for too long, most cars that get a dealer service will have the remote battery changed at that time π
Worth a phone call IMO π
