Project - Making Lockwood 001Touch Keyless Digital Deadlatch Wifi

[kingkongw24]

Hi all,

I've had this project of mine in my head for many years now, I've got this keyless digital lock that's only got a touchpad with a backup 9v terminal on the underside of the touchpad that can be programmed with codes for different people, and I can also add a temporary visitors code but to do this I will have to manually configure it for a said amount of time lets say 5 hrs from the time it was configured then it will expire automatically.

The problem is that if I have a visitor show up, I can currently see them on my security system but can not unlock the door remotely. i will have to give them a passcode that I've already set up as they have just shown up and I have not set up a temporary code.

From my observation so far, the device activates a solenoid for 7 seconds once the correct Pincode is input, once 7 seconds is up then it activates again back to the locked position.
So this lock is a deadlatch, different from a deadlock that most Wifi locks are, as deadlocks retract a barrel then after a while engages, while this deadlatch solenoid active or not, still allows the door to self-close and "latch" into place.

The question is do I find the solenoid wires and have some kind of wifi device (not sure what to use yet) power the solenoid directly and bypass the current PCB or do I find a way to use the board its self to activate the solenoid. The entire lock is powered by 4x AA Batteries.
Either way I need a device that also has a power source that will need to be constantly powered and waiting for a wifi signal to activate some kind of relay that then activates this solenoid for the lock.

Any suggestions on how I should attack the problem and what should I use for the wifi part.

I'm not that confident in tracing and reading boards to find the right terminals and stuff.

The following is the product specs and install images.

Its not worth hacking the lock.   Simply add an electric door-strike.  As it replaces the existing door-strike on the frame, there are no problems getting 12V or 24V power to it. 

Personally, I'd be very reluctant to use WiFi for any sort of access control application.  Manual door release buttons, or an off-the-shelf entryphone system hard-wired to the door-strike would be vastly preferable.   N.B. the wiring *MUST* *NOT* run through any insecure areas.

Very good point can add a simple door strike.


Thank you, prob over thinking it haha
