We've diagnosed every kind of lock failure on commercial entrances. Here are the problems our clients call us about most often.
A worn solenoid inside the strike is the most common cause of this exact symptom. Left unaddressed, the solenoid usually fails completely and stops responding altogether. We test and replace the solenoid or full strike assembly as needed.
A wiring fault or a failing relay in the control panel typically causes this kind of unpredictable release. This is a serious security gap since the door is not reliably secure between visits. We trace the fault to its source and repair or replace the failing component.
A weakening magnetic field, misaligned armature plate, or failing power supply are the usual causes of a soft-holding maglock. Continued use in this state defeats the purpose of the lock entirely. We test gauss strength and power delivery to identify the actual failure.
A misaligned strike keeper forcing metal against metal is the most common cause of this noise. Ignoring it allows the misalignment to worsen until the door stops locking entirely. We realign or replace the keeper assembly to restore smooth operation.
Confusion between fail-safe and fail-secure behavior often causes a lock to behave unexpectedly after power returns. This matters most on fire-rated or egress doors with specific code requirements. We confirm and configure the correct fail mode for your entrance type.
A break in communication between the access control panel and the lock itself typically causes this mismatch. This leaves valid credential holders unable to enter despite a working reader. We test the full signal chain to isolate where the fault actually sits.
A fire alarm interconnect that was never properly wired or tested causes this compliance failure. This can leave a building out of code on a fire-rated or egress door. We test and correct the interconnect as part of every repair on these door types.
Repeated failures on the same entrance usually mean an earlier repair addressed a symptom rather than the root cause. Continuing to patch the same lock costs more over time than resolving the actual issue. We document failure patterns and identify the underlying cause.
Card readers, keypads, and request-to-exit sensors can all cause symptoms that look identical to a lock failure. Replacing the wrong component wastes money without solving the problem. We run a full diagnostic before recommending any specific repair.
We were about to pay for a full maglock replacement when Prime Windows Toronto ran a voltage test first and found the actual issue was our power supply. Saved us a few hundred dollars and the door has been rock solid since. Wish every technician tested before replacing.
Our egress door locked fine but nobody had ever confirmed it released properly during a fire alarm test. The technician caught this during a routine repair and fixed it before it became a compliance problem. That kind of thoroughness is rare.
The solenoid replacement itself was quick and clean once the part arrived. We had to wait an extra day because our specific strike model wasn't on the truck, which pushed things back slightly. Still glad we called them.
Our side entrance was unlocking randomly with no credential swiped, which was terrifying from a security standpoint. Prime Windows Toronto traced it to a failing relay and had it replaced the same afternoon. Genuinely relieved.
I had no idea our egress door needed to unlock during a fire alarm regardless of normal settings. The Prime Windows Toronto technician walked me through it, tested the interconnect, and made sure we were actually compliant. Appreciated the education, not just the fix.
Our front door strike had been making a horrible grinding sound for weeks. Turned out the keeper was misaligned from a slightly shifted frame. Quick fix once diagnosed correctly, and the noise is completely gone now.
