A smart lock is not automatically compatible with every door. Door thickness, existing holes, lock type and available clearance all affect the fit. Photos can help identify the general arrangement, but measurements may still be needed before equipment is ordered. Choosing hardware first can create avoidable installation changes later.
Look at the whole entrance during the initial discussion. A narrow metal frame, a glass panel close to the lock or an existing handle assembly may limit the available options. The inside portion of an electronic lock also needs enough room. Decorative trim and other hardware should be considered before the final model is selected.
Operation matters as much as dimensions. If the door must be lifted or pushed hard before the bolt engages, electronic hardware will not correct that underlying problem. The installer should check alignment and explain any related repair. A suitable lock needs an entrance that closes consistently under normal use.
Send clear photos of the inside, outside and edge of the door, including the current lock. Mention whether the property is a home, storefront or shared building entrance. 770 Doors & Windows can review compatibility and arrange an inspection when needed. The goal is a clear installation plan covering both the hardware and any door work required.
