Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Overview: The Code Alarm DLRK door lock module will allow you to
interface to all typical door lock circuits using 5-wire switching (polarity
reversal), 3-wire switching (both positive-switched and negative-switched), and those circuits
requiring a resistor. The module has a built-in variable resistor (300Ω
to 10,000Ω) and a pair of jumpers, which,
when properly configured for your vehicle, will control the door lock and/or the
vehicle factory alarm circuits.
Mounting Location: The control module is typically mounted under the
dashboard, in a central location where you can access the door lock wires. In
addition, the included 3-pin interconnect harness will be routed and plugged
into the mating connector of the controlling Code Alarm keyless entry module or car alarm.
Systems Requiring an Actuator: Some vehicles (typically Mercedes, BMW,
Volkswagen, Volvo, Saab and Subaru) use a central locking system that utilize a
mechanical lever in the driver's door which manually moves an electric switch by
the key outside or the lever inside, causing all other doors to lock or unlock,
depending upon the direction the key is turned or the lever is moved. In these
applications, a door lock actuator, such as the Code Alarm DA1 (220DA1),
is required. The DA1 will replicate the action of the outside key or inside
