Of course. Metal, HPL or other type of lockers can be easily retrofitted with one of the Metra electronic locking solutiosn. In the process of retrofitting the lockers, the existing locks can be removed or left on locker doors.

In short: Yes. However, it is necessary to choose an open/close combination. Metra electronic locks have three open/close modes or combinations to choose from, depending on your locker installation requirements and needs:

– Auto-open/push-close
– Push-open/push-close
– Pull-open/auto-close

The first two modes do not require locker doors to have handles.

In comparison to motor-driven locks (note: all Metra locks are motor-driven), solenoid locks have good holding but rather poor pulling force (force to power ratio). This makes them sensitive to vibrations, e.g. door slams, and also causes difficulties in proper functioning when there is too much force (tension) on the door from the inside (e.g. a large bag inside a locker).

If by “best” you mean the most convenient way/technology for users to operate lockers, then we would suggest WiFi/4G, for a number of reasons. With WiFi/4G electronic lockers can be opened from anywhere (yes, from anywhere in the world, where your mobile phone has a network signal). Secondly, a user interface is not required to open lockers which a) saves you money, and b) enables the visual appearance of locker installations to stay intact or “clean” (no RFID readers).
The second best option in our opinion is using Bluetooth, whereby lockers can be opened when users are just a couple of metres away from a Bluetooth user interface/reader, still within range of a Bluetooth signal.
NFC (Near Field Communication) doesn’t really provide “remote” locker usage as users have to be within 4cm of a NFC user interface, which is basically the same as with normal RFID cards.
Additionally, Wifi, 4G or Bluetooth technologies are all included in every new smartphone on today’s market, which isn’t always the case with NFC.

The majority of new smartphones need 1A of power to recharge, whilst tablets require even more, ca. 2-2.5A. Some locks do have a built-in USB chargers, but they normally provide only up to 500mA of power. This means that it takes a long time to recharge devices, plus there is a certain electric risk if too many users try to charge their phones and tablets on the same locker installation/electrical grid at the same time. A separate cabling for charging purposes is probably a better (and safer) solution.
