Re: [DML] Original locking module: Really that bad?

[Chris Almy <chris.almy@xxxxxxxxxxx>]

You might want to check out the tech section as it covers the two major 
issues with the lock module. The first and foremost are the relays. The 
problem is they can't handle the current requirements for the solenoids. 
Over time, they will start to stick and cause the solenoids to burn out. If 
you want to keep the lock module, these relays should be replaced. And to 
prevent them from failing again in the future, add another set of high 
current relays that will actually switch the solenoid current. Don't use 
the high current ones directly with the controller electronics as it will 
change the length of time that it engages the solenoids.

The second problem is the standby power. Over time, it will slowly drain 
your battery. There is an article in the tech section that covers replacing 
a set of transistors and resisters that will dramatically lower the standby 
power. While you are at it, replace the capacitors to insure proper 
solenoid engagement timing (their cheap and available at Radio Shack).

If you are not comfortable with soldering the electronics and wiring 
additional relays, then you would be much better off either disconnecting 
the controller or installing a Lockzilla. Otherwise it should only cost you 
about $40-$50 in parts and a few hours of your time.
