ok so the truck i bought came already with an alarm installed called MARKSMAN.. im not to familiar with this brand but it seemed ok at first and now it wont lock or unlock my truck it beeps and everything but it just doesnt seem to lock or unlock the car im thinking it could be a fuse .. but wutt fuse im lost here please help some one.. ive tried locking the car and unlocking it with the switches it has inside the truck but then i try using the remote and nothing it doesn wanna do it..

 

Id look up a schematic for it using the model # and Brand on thier website, or contact them for one. Its kinda hard here to identify after market products and the way they were hooked up. Who knows, maybe someone here can help, good luck!

 

Here's an unusual idea. maybe in using some crazy scheme to produce a profit, Marksman(very possibly a local firm,BTW) made more than one of these bad boys,installed them all the same way, and is still in business.

Try contacting Marksman directly.(Thank you, just send me money,love ya, buh-bye now.)
