Use you other keys !

NEVER remove the battery cables for ANY reason,
other than to replace a failed or worn out battery

Before you do remove the cables, you better check
a service manual for the problems you will have,
even with a simple battery replacement

Some Euro cars need the computer programmed
to recognize the new battery

When you remove battery power, as everyone does, to
clear codes, you lose ALL Data & have nothing to work
with, to even find a problem

We're at the point where your best to leave the car up to
a trained professional

You never remove any wires or even put test leads on
a vehicle, with the ignition on,your asking for trouble,as
you found out

May have to call a shop for help

SOURCE: Automatic door locks will not work.

you need to take it to the dealer and have them check the bcm for codes.... also have them check to be sure you have the latest software in the bcm.. its possible that you just need a software update... there are several TSB's covering the concern you have..... it can be a very simple fix with software or even a stuck lock switch may need to be replaced... without the proper diagnostic codes being read from the bcm all that can be done is guessing..and that can be expensive...

SOURCE: battery went flat cannot unlock vehicle

If you have a battery charger, you could go underneath the vehicle and hook the positive cable to the positive lead on your starter, and ground the ground to the frame.
"Make sure the positive lead is not touching any part of the frame or the starter, except the positive lead".
I would not break a window to access the vehicle, but it is your choice; it's your vehicle.

Other than that, you could do as emissionwiz stated, and use a slim jim to unlock the door.

I personally would use the solution I provided, and use a battery charger. It would only take a few seconds to supply enough power to unlock your doors.

I hope this helps you, and I wish you luck.

cbridges2232,

Any luck with your keyless remote issue? I'm having the exact same problem with my Ford F150 CrewCab after car battery replacement.

SOURCE: can not lock car by key remote . toyota rav 4 53 plate

If your car has an alarm with a separate remote, it is a separate system and it is probably self-arming. When you lock the doors with the key central lock, the alarm gets armed by the RAV4 being OFF and the door locking action. When you unlock the doors with the key, the alarm is still armed because the key is not comunicating with the alarm just the cars factory keyless system.

My 2008 town and country trunk will not open at all with key, inside or even manually. It just beeps and then sounds like it's latching to close again?


central locking fault might just need resetting, if you can get into the vehicle and remove the battery terminal. negative side. leave it off and then open all the doors by hand, and leave the doors open/boot as well. reconnect the battery after a few minuets or after 10min. it should reset. if not then it might be the drivers side lock that's the problem it has switches in there that control alarm and central locking

Tip

Replacing a Car Battery


This Tip describes the correct procedure for changing a car battery.These steps apply equally if you intend to remove your old battery for recharging and then replacing it into the vehicle. Changing a battery is a straightforward process as long as you adhere to the correct procedure. This Tip includes some photos to help aid the process.

a08e2ad.jpg

Common cautions to be aware of before commencing;

Caution 1: Rubber gloves and protective eye goggles should be worn during this procedure as car batteries contain a sulfuric acid electrolyte solution. This is highly corrosive (i.e. can burn your skin) and produces a flammable gas. Do not smoke and keep naked flames away from the work area. Do not touch any old corrosion on the terminals with bare skin. Be careful when handling car batteries - they are heavy - always keep them reasonably level when handling them to prevent any acid spillage occurring. Battery terminals contain lead - always wash your hands after completing this procedure.


Caution 2: Be careful not to cross over the connections to the battery. Red (+) is positive and goes to the (+) Terminal on the battery. Black (-) is negative and goes to the (-) Terminal on the battery.
  • When removing the battery - always remove Negative Terminal first.
  • When replacing the battery always replace Positive Terminal first.

Caution 3: Modern vehicles will have a number of presets that depend on a connection to the battery e.g. stereo, electric seat memory, Sat Nav. etc... For this reason it is recommended to use a memory keeper to avoid any complications that may arise from disconnecting your old battery. A memory keeper simply plugs in to your vehicles cigarette lighter or accessory socket and maintains power to the vehicles accessories whilst you disconnect your old battery. Memory keepers can be powered by the mains supply or some require another 12v battery or 9v battery as a power source - so be sure to purchase one that suits your needs.

You can perform this procedure without a memory keeper but please ensure that you have all the relevant security codes you need in order to reactivate your stereo or any other accessories that will require a PIN code. If in doubt refer to your vehicles handbook.


1) Gather together the tools you need for the job.
  • Your new battery which meets the specification of your vehicle.
  • Wrenches/Spanners for loosening and tightening the nuts on the terminal clamps.
  • A wire brush and sandpaper.
  • Memory Keeper (as described).
  • Vaseline or Battery Lithium grease.

2) Make sure the vehicle is parked on level ground and secured by the handbrake.

3) Familiarize yourself with the instructions with your memory keeper and then plug it in to the cigarette lighter socket.

4) From under the hood identify the battery terminals and clamps. The negative terminal (or battery post) on top of the battery will have a minus (-) sign beside it and the positiive terminal will have a plus (+) sign. In addition to labelling (like on the battery below) these signs will also be indented into the plastic on the top of the battery beside the battery posts.

5) Remove the negative terminal clamp first - using your wrenches loosen the nut (circled below in red) and remove the negative terminal clamp. Removing the negative terminal first helps to avoid any short circuit occurring during the procedure. See below an example of a negative clamp with identification marks circled in black.

6) Next remove the positive terminal clamp.
9201a92.jpg
7) There will be a battery locking mechanism holding the battery in place and clamping it to the vehicle - usually a metal bar. Remove this and then carefully remove the old battery.

8) Next clean the terminal clamps and the battery tray using the wire brush. You may also use some fine sandpaper to clean the inside of the clamps. Make sure you are wearing the safety gloves and goggles during this procedure. Remove as much corrosion and dirt as you can. This helps ensure a good connection to the new battery when you reconnect.

9) Put your new battery in and secure it to the vehicle with the locking mechanism.

10) Reconnect the battery by attaching the Positive terminal first and tighten the clamp with your wrench until you have a good tight connection.

11) Reconnect the Negative Terminal and secure as above.

12) Once the connections are made, you may coat the terminals with ordinary Vaseline or Battery Lithium grease to help prevent further corrosion.

13) Remove memory keeper from cigarette lighter socket. Shut the hood and the job is done.

My battery was bad, so I had it replaced and the car worked fine for a few days. One day while out running errands I went to start the car and nothing happened. No sounds, etc. All of the lights work...


Sounds like you have a dead battery again. Who install you battery? Did they check out the charging circuit on your auto. If a professional mechanic installed your battery then have him check everything out; such as, cleaned battery terminals, the ground strap is solidly connected the body, charging system is working. If a professional mechanic didn't install you battery.


Remove the battery from the car/truck and have it fully charged. Clean the ground and positive terminals with wire brush until the lead is bright and all the corrosion is gone. Clean the battery terminals until the batter terminals are bright. Get a couple anti-corrosive felt disk---they look like two big felt washers, one red (+) and other is black (-). Insatll the battery and make sure the terminals are tight. Start the car/truck and while the vehicle is running take a voltage test across the battery with multimeter, volt meter, etc. The voltage across the battery while the vehicle is running should be 13.8V to 14.1 volts. If not, Have the alternator check out!

Like you said you have had everything check out. Check it out again. If everything check out again then there is a internal component, wiring shorted which pulling current the battery and could drain the batter of current within a few days.



If you are using your car for a few days to running errands. You car will run on the battery with no charging cycle working. Once the battery voltage falls below a certain voltage point the computer will only limit certain electrical components work, door locks, maybe one window and this is iffy! The reason why you can't get the transmission out of park is the locking solenoid that operates with the brake switch will not function. This function is a safety procedure that is Incorporated within the vehicle design. . GB...stewbison

What size does battery does it take and if i change the battery will it lock the whole car up or do I have to take it to the dealership


this vehicle takes a 65 series battery. step one is to disconnect the negative terminal. step two is to disconnect positive terminal. step three is to remove battery hold down which i believe is held down by a 8 m.m. bolt located in front of battery (side facing engine). inspect terminals for acid corrosion if needed clean before connecting to new battery. keep keys in pocket in case doors decide to lock one new battery is connected. installation is reverse of removal. if this was helpful please leave positive rating.

NEED TO REEPROGRAMING A REMOTE CONTROL FOR A MALIBU 1998 HOW '?


1. Make sure ignition is in the OFF position.
2. Locate the Programming Connector in the trunk (center of rear shelf). It is a plastic connector with
two wires leading up to it. The connector is not plugged into anything. You may have to pull back
trim to access the connector.

3. The programming connector should have two terminals. Connect both terminals with a suitable
jumper wire. The Keyless Entry Module will lock then unlock all the door lock motors once. Make
sure the terminals remain connected throughout the programming procedure.

4. Press and hold the LOCK and UNLOCK buttons on the transmitter simultaneously for at least 15
seconds or until the vehicle automatically locks and unlocks the door locks. Your new remote has
been accepted and all existing remote codes have been erased.

5. Repeat the previous step for each transmitter to be programmed. Do not remove jumper wire in
between programming of transmitters.

6. Remove the jumper wire from the Keyless Programming Connector.
