Alarm Lock SP103 – Frequently Asked Questions

1) What exactly is the Alarm Lock SP103?
The SP103 is a lock case, the mechanical housing that carries the latch and bolt works inside an Alarm Lock mechanical lock. It is sold as an Alarm Lock replacement part, not as a complete lockset, so it goes to a technician servicing a lock that is already hung on the door.
2) Is the SP103 lock case a complete lock, or do I still need trim and a cylinder?
It is the case only. You get the mechanical housing that supports latch and bolt operation; levers, trim, cylinder and strike are not part of it. If the existing lock's trim and cylinder are serviceable, swapping the case restores the unit without buying a whole new lockset, which is the point of ordering the part rather than the lock.
3) Will the SP103 case fit any brand of mortise lock, or only Alarm Lock?
Only Alarm Lock. The SP103 is an Alarm Lock replacement case for compatible Alarm Lock mechanical lock systems. Lock cases are brand and series specific, so match the case to the Alarm Lock model already in the door rather than assuming it drops into another manufacturer's prep.
4) Is the SP103 lock case rated for commercial use or is it a residential part?
Commercial. Alarm Lock classifies the SP103 as a commercial part, and it is the kind of component stocked for office buildings, schools, healthcare, retail, warehouses, multi-tenant housing and municipal buildings where doors see heavy daily cycling.
5) How many versions of the Alarm Lock SP103 are there to choose from?
One. The SP103 is a single-configuration part with no finish, handing or size options to specify, so the order is just the part number itself.
