Dear,
Though i can't help you much on ur issue. But better check from expert autoelectrician for this.
Regarding keyless entry, i have some real good word and wanna share with you.
Keys Locked in the Car?
This may come in handy someday. Good reason to own a Cell Phone: If you lock
your keys in the car and the spare keys are at home, call someone on your
cell phone. Hold your cell phone about a foot from your car door and have
the other person at your home press the Unlock button, holding it near the
phone on their end. Your car will unlock. Saves time for someone to drive
your keys to you. Distance is not a problem. You could be hundreds of miles
away and if you can reach someone who has the other remote" for your car,
you can unlock the doors (or the trunk).
