AutoLoc eliminates the confusing button combinations and headaches that come with most 3 and 4 channel remote systems. To activate the third or fourth channel, most remotes have you pressing all sorts of hard to remember and time consuming button combinations. With AutoLoc’s new TR-2 remote control, activating the third or fourth remote function on your vehicle just got a lot easier. With two ‘dedicated' activation buttons, you can engage your two favorite functions with just one touch. To access your third channel, simply press both ergonomically designed buttons. Your fourth channel is activated by holding down button two for 3 seconds. AutoLoc makes having a full array of easily accessed remote controlled functions a reality for you and your vehicle. In just seconds you can unlock your doors, roll down your power windows, switch on your dome or headlights, roll your windows up or down, or anything else you can think of on your vehicle (AutoLöc KL 4950 receiver required) Featured on several TV shows including Monster Garage, and Pimp My Ride AutoLoc kits deliver where all others fails. Insist on the best, and insist on AutoLoc and you be glad you did.
