If you are finding a mag (electromagnetic) lock to be “sticky” or slow to release it is likely that it has a diode connected across the power terminals. Remove it, problem solved. This is a common mistake.
If the lock does not immediately release or seems to be \"sticking\" then first check the power connections at the magnet with a volt meter and confirm the voltage is dropping completely to 0. If there is residual voltage then check the control relays and field wiring in the system.
Final answer: To turn off an electromagnet, disconnect the electric circuit to stop the flow of electricity. This discontinues the magnetic field that is generated by the current flowing through the wire coil and around the iron core.
Simply push the button and pull the handle if you want to go outside. You might be wondering, how does one unlock the lock if the power cuts off? The truth is you don't have to worry, you won't be trapped inside. If the electricity is shut down, the lock will automatically unlock itself.
One of the most common problems with maglocks is a power failure. This occurs when the lock doesn't release or engage due to a lack of power. Possible causes of power failure include a dead battery, a tripped circuit breaker, or a malfunctioning power supply.

Most maglocks will also have an anti-residual magnetism facility, which is usually a small "thrusting magnet", designed to repel the magnet from the armature plate when power is removed from the magnet. The door will then open as any residual magnetism is broken.
Maglocks have fewer moving parts and are frictionless. Therefore, they don't wear the same way a latch or strike would, which leads to long-term durability. Once installed, maglocks require very little maintenance. If using a maglock, the access control will outlast the door it is installed on.
The easist way to keep a magnet from sticking to other stuff is to keep it away from the other stuff. The forces of attraction and repulsion get very small far away from the magnet. You can also redirect the magnetic flux lines into a loop to reduce the field strength away from the magnet.
Moving charges create magnetic fields, so when the coils of wire in an electromagnet have an electric current passing through them, the coils behave like a magnet. When the electricity stops flowing, the coils don't act like a magnet anymore.
Maglocks can run hot due to the electricity running through them. It's that same electricity that creates the electromagnetic field used to secure doors and gates. If the maglock appears to run much hotter than you'd expect, it might be best to contact us for a free site survey.
Some of the most common culprits include: Dirt and Debris. Over time, dust, dirt, debris, and even broken pieces of your key can accumulate in the lock mechanism, hindering its smooth operation. This build-up can lead to a situation where the key turns, but the lock won't open.
If you have a stuck door lock, spray lubricant into the lock's keyhole. Doing so will loosen any debris or deposits sitting inside your stuck lock and prevent your key from turning. Insert the key and rotate it a few times to work in the lubricant, releasing the stuck part.
Use a can of compressed air or a small brush to clean the keyhole thoroughly. Lubricate the lock: Sticky locks are often due to a lack of lubrication. Apply a graphite-based or silicone-based lubricant specifically designed for locks. Avoid using oil-based lubricants as they can attract more dust and grime.
Use Graphite Powder
Graphite powder is an excellent lubricant and a great way to fix a lock that is becoming difficult to unlock. Powdered graphite lubricant can be bought in small bottles made of soft plastic with a nozzle, meaning it is easy to squirt a small amount of lubricant into the lock.
What's the best lubricant for your lock? When choosing the best product to lubricate locks, dry lubricants like graphite powder and PTFE lubricants are best. As mentioned above, oil-based products can attract dust and dirt which can damage the delicate internal mechanism of your lock.
Possible Problems
The latch may not be properly placed in the electric striker, the magnetic lock may not be properly aligned due to mechanical force or weariness, and the power supply to the striker can be insufficient.
If you're expecting freezing temperatures, spray some WD-40 into your lock and the lubricant will take care of things. Be sure to get the lubricant inside the lock, though. Spraying the outside won't do you any favours. So, place the nozzle right up against the lock opening and spray for around 3-5 seconds.
Inspect and Clean the Lock
If dirt or debris is present, use a lock lubricant spray or compressed air to clean the lock cylinder. Insert the key and gently wiggle it to help dislodge any particles. Avoid using excessive force, as this can cause further damage.
One of the most common reasons people find their door isn't locking is because of a misaligned door. Whether it's because of the door itself on the hinges, how it fits in the frame, the striking plate or the location of the lock, a misalignment can mean your door won't lock properly.
Door lock problems are often caused by a malfunctioning lock mechanism or latch assembly, but there are several common reasons why locks stop working: The lock is dry or dirty. It doesn't fit in the door properly. The latch and strike plate don't align.
