Today we will be examining the magnetic keyed lock. We will talk about it’s pro’s and cons and even take the time machine all the way back to 2005 where we take a look at a retro lock that people were using back then.

In the last 10 years Electro-Magnetic locks system (MAGLOCKS) is being mostly used too much, and although there is surely a use for them in the market location. They have their some limitations also, and in some examples must not used at all.

Maglocks are economically and easy installed with a L or ZL bracket on most wooden or aluminum  doors, as well as steel gates. But there is no want to cut into the aluminum where under normal circumstances limited tools. And also a some amount of skill required to install a electrical mechanical lock – which most fitters do not have. Hence they install a maglock regardless if it is correct for the application or not. Fundamental rule of thumb is not to install a maglock where the cabling is reveal.

There are several divergence between a electric lock as well as  a maglock. Moreover, one of the biggest divergence is the fact that an electric lock works on a generally open electrical circuit, where the magnetic lock works on a generally closed circuit.

Electrical lock

What this means that there no power to a electrical lock and only once the release button pressed or the Electro-Magnetic locks  system activated. In any another way, the circuitry fully closed and the pulse of power to the electric lock permits the cylinoid to free the deadbolt and the lock kicks gets open. Hence, if there is a electricity failure the lock stays forever closed and can only opened manually with a key.

A maglock should have power on it any time to stay closed and as soon as there is a electricity failure, it will automatically open. Correspondingly if the cable to the maglock is not invisible out of sight, it can be destroyed and the door/ gate will open. Even if the electricity to an electric lock is cut, the gate/ door remains closed. This is one of the biggest drawback of a magnetic lock.

The magnetic keyed lock uses (surprise, surprise) magnets for the locking and unlocking mechanism. A magnetic key use magnetic force to manipulate the tumblers inside a locking mechanism, as opposed to a traditional key which uses mechanical force.
