What goes wrong
Commercial doors in Malvern often fail at predictable points: a cylinder that won’t turn because the key is worn or the plug is damaged, an exit device with a broken tailpiece, or a latch that no longer meets a reinforced strike because the door has warped. We come to the job with the tools and parts to diagnose whether the lock needs rekeying, a new cylinder, a replacement mortise lock, or just a realignment of the strike and latch. We explain the practical fix and the hardware involved so you know what we’re doing.

What the job involves
When an exit device jams or a panic bar won’t retract, the immediate job is to get the door operational and safe for use. We remove the trim, inspect the internal parts, replace broken springs or rods, and check the interaction between the latch, strike, and door closer. For electric strikes and access control failures we test the wiring and power feed, swap in known-good components, and confirm the keypad or card reader is getting power and communicating with the lock mechanism. We drive out from Havertown with stock parts for common commercial hardware.
03
Good to know
While we work, keep staff and customers away from the affected doorway and have someone available who knows who is authorized to receive new keys or approve changes to a master key system. We cut and hand over keys on site when rekeying or when adding a cylinder, so have photo ID and written authorization ready for anyone receiving new keys. If the job involves access control, gather any existing key lists, wiring diagrams if available, and the keypad codes you want changed so we can program or synchronize devices without guessing.
04
Worth knowing
Commercial jobs often require tweaks beyond swapping a lock: tweaking door geometry, reinforcing the strike with longer fasteners, replacing a latch with a long-throw deadbolt for better engagement, or installing a new rim cylinder to match a master key system. We can rekey suites, set up hierarchical keying, repair or replace door closers, and fit replacement strikes that sit flush and engage solidly. If panic hardware or an automatic operator is present we inspect their interaction with the lock hardware and recommend practical hardware swaps or repairs to restore reliable operation.
