audiovox elvat5c f150 1999 remote broken

Find the module it is a black box (like 4 packs of cigs side by side).  You might have to take apart the lower dash to get to it(depends on where the installer mounted it).  Anthor place to look is under the driver dash put your body and head low at the brake switch and look to the left you will see a large wirirng harness coming from the fire wall it might be in that area.  Once you find the module it might be wire tied.  Cut the wire tie.  Look at the module and see if there is a 2 pin plug in the blue port.  If there is trace the wire coming from that plug and it will lead you to the push button.  The push button looks like an eraser head on a pencil and its black.  Once you find it turn the key on to the on position(your check engine light & oil light will come on).  When you see that you have 10 seconds to press firmly on the button and release it.  The alarm will shut off so you can start the car.  Hopefully the previous owner didn't put a personel code in.  You will know if they did, as soon as you turn the key on you will hear a weird siren blast.  If you hear that then you have no choice to send in that module into Audiovox and they will have to reset it.  Once you get the car started you will have to reprogram the remote.  If you don't have the owners manual of the alarm get back to me, On the module there's a series of numbers starts with S/N or P/N.  Give me those numbers and I can tell you what module you have.  Then you can go to the www.audiovox.com and down load the owners manual and it will walk you through how to program the remote.
