This keyless entry system is the perfect fit for your Mercedes Benz
SL-Class W107*** 1972-1989. It allows you to lock and unlock the doors and trunk with a push of a button using the new FOB remotes*. A parking light flash provides a visual confirmation. It also has two outputs for other accessories such as window module or trunk release module, or can be used for factory alarm activation.
One good reason to install this system into your Benz is that it will take the load off of the lock cylinder links, which are known to break often.
This complete keyless entry system has everything you need for installation. You will get an installation manual complete with a wiring chart for the do-it-yourself installer, as well as a professional installer’s guide. In addition, you will receive technical support when needed, by phone or E-Mail.
*** Earlier models (72-84)

system is compatible with this set up as well. To find out if your W107 needs an actuator in the driver's door, please contact us.
