Storefront Door Locks in San Jose

Aluminium-and-glass shop doors on Lincoln Ave, in Japantown and around Santana Row: deadlatches, pivots and the closer everyone blames the lock for

A storefront door is a different machine from a house door and it fails differently. It swings hundreds of times a day, it is aluminium and glass rather than timber, and the lock in it is usually an Adams Rite style deadlatch in a stile barely more than an inch and a half wide. When one of these stops working, the phrase used on the phone is nearly always "the lock has gone". Perhaps a third of the time it has. The rest of the time the door has dropped on a worn pivot, or the closer has lost the pressure that pulled the leaf the final half inch, and the latch is simply arriving somewhere the strike is not.

So the visit starts with the door leaf. Top and bottom pivots are checked for wear, the gap along the lock stile is looked at along its length, and the closer is tested for whether it still brings the door to a positive latch rather than nearly there. Only then does the hardware get judged: the deadlatch and its auxiliary bolt, the strike in the frame, the mortise cylinder and its cam, and the thumbturn or paddle inside. Common outcomes are a strike moved by two millimetres, a closer adjusted or replaced, a deadlatch swapped after a decade of use, or a cylinder changed because a former keyholder is the actual problem. Where the whole door is out of square because the frame has moved, that is said honestly, because a new lock into a bent frame is money into a hole.

Storefront work is $155 to $465. A cylinder change or a strike adjustment on a sound door sits at the bottom. A new deadlatch, a closer, a pivot set, or a pair of doors where both leaves need attention runs to the top. Hardware is named separately before it is ordered. The $89 visit is inside the figure; between 8pm and midnight the $155 job reads $195, overnight $230 — and after hours is often the right time here, because these doors cannot be worked on while customers are coming through them.

Two things that save shops money. First: when a deadlatch is replaced, the auxiliary bolt matters more than the main one — it is the small plunger that stops the latch being carded, and a worn one is why a door can be opened with a plastic sheet. Second: if you have more than one unit, or a back door onto a service alley, ask to have them keyed alike on the same visit. Most independent shops here run three different keys for three doors for no reason other than that they were fitted in different years, and a staff member holding three keys will prop one of the doors open by summer.
