replace batteries in remote & charge battery on car, you will need to "Break" into your car you can do this by wedging the door from the top back corner & using a wire coat hanger to activate the door locking mechanism on the inside, once open, unlock all doors manually then remove battery for recharging,

Key?...lol..some trucks have a latch on the inside if u can fold down seats enough to reach it...

Two options you can try. 1st, lock and unlock each door manually with the key including the trunk, then try to start vehicle. 2nd option, with vehicle battery, turn the ignition to the 'on' position, reconnect the battery then try to start the car.

Assuming the car battery is ok (if not, buy a male to male cigarette lighter at the auto store and connect to another car until charged enough to unlock the doors...but don't try to crank the ignition!). The trunks won't open if the battery went dead with the alarm set because arming the alarm physically locks the releases.

Sounds like the key code is switched off because you replaced the key fob battery. Try unlocking the car manual with the key in the door lock. Then switch the ignition on to reactive the keyless entry. If this does not work, you might also try pressing the fob unlock button with the key in the door lock until the dash led flashes.

open trunk, disconnect rear trunk light. use jump box and connect wires to pos neg on jump box. this will give u enough juice to open doors, I have done it twice. easy to do

you can charge the battery from the engine compartment. check your owners manual that is the correct place to jump and to charge the battery.

I simply opened the bonnet. Connected the battery charge positive to the + feed on the back of the alternator, connected the negative to the body. Turned it on, immediately the interior light comes on. Turn on the ignition press the cabin boot switch and it opens the boot. Charge battery as normal. Easy Peezy

cover under bonnet with a big P on it and negative is anything metal on the engine
