Onstar Lockpick Installation Instructions

Start with the car and radio turned off. The GM LOCKPICK is designed with a "T" harness, equipped with factory male and female connectors for direct connections to your screen. With access to the rear of the screen, unplug the matching Black connectors and plug them into the female connectors of your LOCKPICK. Then plug the male Black connectors of the LOCKPICK harness into the earlier factory locations. The connectors are keyed and cannot be plugged in to the wrong location. Slide the blue locking tabs on the top of the connectors back before attempting to insert the plug fully into the radio. Do not plug in the LOCKPICK yet.

Next, determine the switch setting you desire for your installation. Start with all switches in the UP position. Then set switch five (S) to the down position. This setting programs your LOCKPICK to work with all of the above 2007 vehicles. If your vehicle is equipped with ONSTAR, set switch four to the down position also. Most installations will be with this configuration (1,2,3 UP - 4,5 DOWN).

After positioning switch 4 and 5 to the desired setting, plug the box into the LOCKPICK harness. If you wish to change the switch setting after plugging in the controller, the car must be turned off and the box unplugged first Then change the switch setting and plug it back in.

Your handsfree kit will need connections for power, ground, mute and audio. Your ONSTAR LOCKPICK provides these connections on the harnesses provided. Connect the Yellow wire labeled MUTE, to the mute connection on your handsfree kit. Connect the Red 12 ACC power provided by the LOCKPICK to the accessory power connection on your handsfree kit and the final Yellow constant power on the LOCKPICK harness, to the 12V constant or battery connection of your handsfree kit. Connect the line level audio out to the wires provided on the ONSTAR LOCKPICK harness.

It's as simple as that to use your ONSTAR for your aftermarket BLUETOOTH handsfree kit. For most installations, the disassembly needed to get to the rear of the screen/radio will consist of "popping" loose the trim around the face of the radio to expose the 7mm bolts holding the radio in position. Remove the screws and the radio can be tilted rearward to view the connectors needed. The trim around the face of the radio is held in place with spring loaded friction locks which sometimes can require some pressure to release. A video and photos have been provided on the Coastaletech.com website to provide you assistance. The video describes the installation of the GM DVD LOCKPICK, but the process is similar.
