Electronic Cabinet Lock

I am just getting into the hardware side of things after programming professionally for many years. I have an idea for my first project but I am having trouble finding 'reasonable' components and was wondering if anyone else has had the same need or any other suggestions.

What I want to do is provide a membrane keypad lock for a small trunk (hence not being able to use a strike plate). The lock I listed above would work great; however the WAF on that pricing is very low to say the least, also I don't need a TON of security, just something to keep honest people honest.

My first idea was to use a magnetic lock but then thought against it due to power, so I 'settled' on some sort of mechanical lock with possibly a reed switch for the circuit power.

Thank you in advance for any suggestions.

Your first post can't contain links (spam prevention), so repost the link, ok?

Any kind of locking mechanism you are controlling with the Arduino is likely to be electric; so I am not sure what you are meaning when you say you don't want it to be so?

What I would do instead is make the Arduino an alarm device; it will give you some experience in a variety of areas (blinking LED, arming/disarming with keypad, plus sound for alarm and feedback), but make the actual lock mechanical and magnetic.

Set the lock up so that with a powerful magnet (like a rare-earth magnet), the lock will disengage; with a trunk this could be a simple lever-action device on the inside top front lip, so that when the magnet is stuck on it, it tilts forward, disengaging the latch below (like a see-saw).

Alternatively, you could just use a regular lock, or a combo of things, to make things as easy or difficult as you like...

"Truck" as in of a car?

What power source do you have in mind for this?

What is "WAF"?
