The negative chord for the battery is off but when i put it on and tighten it the alarm goes off. The alarm is very sensitive and even when the car is open and im inside it goes off with just a small movement. I waited for the alarm to stop to put the key in the ignition. I tried to start the car but it wont start. I drive a 95 civic lx sedan how can i fix this problem?

The alarm and immobilizer needs to be reset. It is not as straightforward as normal. You may need an auto locksmith.

all you need to do is grab a wrench and loosen the bolt on the battery terminals take them off put the battery then re tighten the bolts and then your done oh yeah makes sure RED GOES TO PLUS SIGN AND BLACK GOES TO NEGATIVE SIGN. Have a good day

look in the book for where the sensor/fuse is and pull it. however; it may be wise too watch your sxplorer during the night when the alarm goes off, it might mean sumone is violating the semsor space?? dog,human,cat,deer,bear??

Check your battery connections for corrosion. Take off the negative and then positive connection to the battery. Clean the posts and terminals. You can use baking soda mixed in hot water to clean them. Be careful not to get the solution near the vent caps. Once clean put the positive terminal on and tighten. Then put on the negative and tighten. Check the battery voltage with a volt meter for more than 12 volts, 12.6 is normal. Try to start the car

Take out the battery , fully charge it over night , reconnect and done...
If not adjust the sensitivity screw on the alarm...

hi, this could be you have not reset the ALARM, when you toke the battery off. please undo the NAGATIVE lead OFF the BATTERY and hold the battery lead ON (for 2 seconds) then take battery lead OFF. you will hear the ALARM make a funny noise (this resets the alarm), put the battery lead ON again and the alarm should SOUND then tighten the NEGATIVE LEAD TO THE BATTERY. if not you need to get the ALARM TO SOUND, need to undo battery NEGATIVE and do the same as above. there is a knack to it. then this will work. THE SYSTEM IS LIKE THIS FOR SECURITY RESONS. gerry
