Security light on car wont start

Could be the battery or alternator. Try this. Disconnect the battery cable, either neg or pos doesn't matter. Leave it unconnected for 5 minutes. Then reconnect. Be sure to tighten screws/bolts that hold the cable clamp in place securely. A loose cable will cause the kind of alert you cited, but if the disconnect resets the entire electrical system, it may not re-occur. Other than the two parts mentioned, there aren't any other parts that would cause the problem. Or maybe a "short" in another area.....try the disconnect first. Good luck Michelle.

start with fully charging your battery.

check if security light is on wile cranking or may blink

you wont fix it take it to a auto electric . unless you got a lot of time . thers a short in harness gonna have to trace each wire ..oh boy oh boy

1st of all Read Your owners Manual, Depending on the Radio you have in it will depend on the Alarm system . Also Completely Disconnecting the Battery Will Reset your Security System

try disconnecting the battery should reset the system

sometimes turning the ignition on 3 times quickly without starting will reset the computer. If the van has power locks and keyless entry then try using only the keyless entry. Sometimes your car wont have a alarm but an anti theft device which will not allow it to start if it goes off or something triggers it.

Try disconnecting battery and let sit for a while to reboot computer.

Need more info. Does it turn over and not start? Does it not turn over? Have you tried to jump start it?

i had the same problem on my 98 sonoma. for some reason your passlock system did not recognise your key and went into security. you have to take it to a dealer or a shop with a computer and have them reset your passlock. if you have a buddy or know someone with a scan tool they may be able to do it to. i think the shop here charged $35. but there is no other way to fix it.
