A good place to go if you drive an older Mercedes and want keyless. Audio 2000 is experienced with working with Mercedes' vacuum based central lock system (most cars use electric solenoid/motors). They installed an Avital keyless system to my W124 E320 and it works like a charm. Virgil was very knowledgeable when I called the day before and I felt confident about them handling the vacuum locks. If you're driving an old W124, W126, W140 or W201 Mercedes, I highly recommend taking your Benz in and installing a keyless entry for you car. It's exponentially more convenient and reduces wear on the door lock cylinders (which are known to break over time).
