Price: ~£100 including bluetooth module and 4 key fobs (mid-2016)
This lock was easy to fit, and only needed one hole to be drilled all the way through the door.
This is a "latch" style, where the bolt goes in to a receptacle attached to the door frame, so no chiseling of the door frame is required. Three different thickness shims are included in case the door does not align with the door frame properly.
To configure a combination, you have to remove the battery cover, and press the "I" button, then type in the number sequence required, and then press "I" again. Up to 20-digit coes can be used.
To add RFID key fobs to the lock, press the "I" button, then on the outside of the door you touch the RFID fob to the the card symbol, and the lock beeps.
A number flashes up on the combination keypad, which increments every time you put a new fob on the card symbol.
When you have finished adding all the fobs, you press the "I" button again, and the lock beeps again.
The manual does not explain how to remove unwanted/lost keys, and we had to work this out ourselves.
There is no way of removing one key if it is lost or stolen.
They only way to do this is collect all the fobs, and then go through the process above again (which wipes all the previous fobs that were registered).
This means that this lock is not very good for places where it would be difficult for people to all give their keys in at the same time (ie rented accomodation).
Fobs from the Gateman Jet also work with this lock, which may give you some extra design choices.
According to one website, this lock conforms to the ISO 14443a standard for key fobs.
The bluetooth module is optional, and is very low power. On our standard Victorian solid wood door, the phone had to be placed touching the door to the right of the outside keypad before the lock would activate, although this is not a bad problem from a security point of view.
There is an button to select whether the lock stays unlocked when activated, or locks automatically once the door is closed again, which is useful if you are going in and out a lot and don't want to keep using the key/combination or leave the door ajar.
To use a RFID fob, you press the button and then hold the fob to the card symbol on the lock.
To use the combination, you put your hand flat on the combination area, type the combConsination, and then put your hand flat on the conbination area again. This process, although seeming odd at first, means that you smudge or obscure the specific numbers you have pressed with your fingers.
To use the bluetooth option, you put your phone close to the lock (without pressing anything) and it activates.
Either press the "Open/Close" button or twist the knob to physically retract the bolt.
This lock takes 4 AA batteries, which are supposed to last for around a year.
If the batteries run out, there is a flap on the outside that you can open and touch a 9V PP3 battery to and then operate the lock.
