Locksmith in WestmountBusiness doors in Westmount,
kept under control

A deadbolt keyed on both sides is sometimes suggested for doors with glass beside them, but on a main escape door it means finding a key to get out. A door people use to leave the home should open from the inside without a key or special knowledge, especially in an emergency. A single-cylinder deadbolt with a thumb-turn, paired with a reinforced strike and a proper glass film if needed, keeps both security and a clear way out.

A restricted or patented keyway is one whose blanks are supplied only through the manufacturer's authorised channels, so duplication is controlled rather than available at an ordinary counter, though the exact authorisation step varies by program and is not always a signed letter. For a company with staff turnover, cleaners and contractors, it means the keys in circulation are far easier to track. It can be introduced during a rekey, on the exterior doors only or across the whole premises, and works alongside a key register.

It is rare, and it is discussed before anything changes. A glued, jammed or corroded-in fragment can usually still be reached by taking the cylinder off the door and working the plug out from the back. If even that fails, the cylinder is drilled where plug meets housing, sacrificed and replaced on the spot with new keys cut, so the door locks normally by the time the locksmith leaves.

Whether the police have been called and any occurrence number; whether everyone is safe and the property is empty of intruders; which opening was forced and whether it closes at all; whether the damage is to the lock, the frame, the door or the glass; whether keys, remotes or codes were taken; whether you own, rent or manage the property; and whether there is glass beside the door.
