1) That's some pretty sloppy security on the part of the lock maker. Someone at that company should be flippin' burgers instead of designing lock hardware & code.

2) That circuit could be made MUCH smaller with surface mount parts.

3) The text says that the data line idles high @ 3.3V. That circuit could probably be redesigned to run off the parasitic power from the data line and eliminate the need for a battery.

4) I'll remember to never leave anything of value unattended in my hotel room. (Not that I ever do anyway)


That is all.

this is assuming you stay inside your hotel room 24/7? then what would have been the point of going on a vacation if you are going to stay inside the room?

If you think that this is sloppy, check out the new trend in car thefts. Many alarms have blind spots on the motion sensors. European (right hand drive) cars seem to have an especially problematic blind spot right next to the driver's door.

http://www.networkworld.com/communit...l-keyless-bmws

This combined with the EU's insistence on making Engine Control Unit schematics/programming available to the open market (to keep the dealerships from keeping certain functions such as programming new keys "in house") and enterprising former Soviet bloc/Chinese companies means that you can break the driver's window, insert a cable through the window into the OBD port and program yourself a new key.

It takes about 2 minutes and at that point they can use the key to disarm the alarm, shift into neutral (for automatics) and push the car far enough away that you won't hear them drive off.

One UK county had more than 300 reported car thefts in a single month via this tactic. The biggest target seems to be BMW, but there are multiple brands affected. Audi seems to have been smart enough to require a call in to the national center before key programming so they don't seem to be affected.

The trunk monkey is more reliable. I hope that they come out with a mobile version soon.
