FAQ
Will this key work with my vehicle’s alarm system?
The Model 448562 is designed for mechanical brake support and keyless entry functions. It does not contain transponder chips, so it will not interact with electronic alarm or immobilizer systems.
Do I need to program the key after installation?
No programming is required. The key’s cut pattern is engineered to match the lock’s mechanical pins, providing immediate functionality once installed.
Can I use this key as a spare for multiple vehicles?
Because the key is cut to specific lock specifications, it is intended for a single vehicle model. Using it on a different make or model may result in improper fit or damage.
