What goes wrong
Commercial doors get used hard and the failures we see are the same ones over and over. Exit devices that bind, latch rollers that shear, cylinders with broken tails, panic bars with warped linkage, and strikes that pull loose from soft frames are common. We diagnose by testing the bolt throw, inspecting the strike and frame reinforcement, and checking whether the door is true in its plane. For electric strikes and magnetic locks we check power, ground, and the integrity of the wiring before swapping hardware or cores. We repair or replace the part that is actually failing, not what looks old.

What the job involves
When an access control system hiccups the cause is often a dead battery, corroded connector, loose terminal, or a controller that needs a reboot. Keypad units and prox readers are usually retrievable by checking backup batteries and the backup power feed, and by confirming door position switch signals. For master key problems we trace the hierarchy, check for incorrectly cut keys or added unrestricted blanks, and inspect pinned cylinders for shear or extra springs. We lay out the options clearly: rekey the existing cylinders, install a new core system, or replace the cylinder with a different physical security feature.

Good to know
If you call from Brookhaven we drive out from Havertown and bring the tools and parts for common commercial work: spare cylinders, replacement cores, deadbolts, reinforced strikes, exit device parts, door closer spindles, and basic access control supplies. While you’re on the phone tell us which door it is, whether it’s inward or outward swinging, and whether it’s metal, wood, or aluminum. It helps to have any existing keys, the building manager or key custodian on site, and access to the electrical room if the problem involves controllers or power supplies.

Worth knowing
While you wait, secure the area by using alternate exits, locking off the faulty door if it will not latch, and posting a temporary notice for staff and customers if needed. Have available any paperwork that shows you manage the space, serial numbers on the hardware if you kept them, and a list of affected suites or units. If the door has a panic bar, try to avoid forcing it; if an electric lock is involved leave power on for diagnostics. We’ll work through the hardware and wiring and explain what we changed and why before we leave.
