Automatic Doors Need Specialty Lock Integration
Automatic sliding, swinging, and revolving doors operate differently from manual doors — and they need lock hardware that works with the automatic system, not against it. You can't just bolt a regular deadbolt onto an automatic sliding door; the lock has to integrate with the auto-open mechanism so:
- The door doesn't try to open against an engaged lock (damaging the motor)
- The lock can be disengaged automatically during business hours and engaged at close
- Emergency exit still functions per code regardless of lock state
- The lock survives the cycle count of an auto door (often 1000+ cycles per day)

Common Automatic Door Lock Issues We Address
- Lock won't engage at close — Worn lock mechanism, misaligned strike, or controller programming issue
- Lock won't disengage in the morning — Mechanism stuck or electrical issue
- Door doesn't latch at close — Strike misalignment or lock wear
- Lock works manually but not on auto schedule — Controller / timer programming
- Lost or worn key — Replace cylinder, rekey, or upgrade to high-security
- Damaged auto door lock from impact — Cart strike, vehicle damage, vandalism
- Code-compliance failure on automatic exit — Auto doors must allow emergency egress even when locked; we fix configurations that don't
What We Don't Do
To be clear about scope: we service the lock hardware, key cylinders, and lock integration with automatic doors. We don't service the auto-door operators themselves — the motors, sensors, controllers, and door panels that make the door open and close automatically. For mechanical / electrical issues with the auto-door operator, you'll need an authorized service provider for your specific brand (Stanley, Horton, dormakaba, etc.). We work alongside those specialists when both lock and operator service is needed.
