Sounds like you have a defective alternator.

SOURCE: keyless remote wont work, vehicle completely shut down

Hi Russell,

Absolutely no power? No dome light? No head lights? Nothing?
When you step on the brake pedal, no brake lights?

If true, start at the source and pop the hood.

This is going to be a bit of back and forth dialogue. I'll ask some questions and you get me the answers. That way we can get to the root of the problem. To save time, I'll ask multiple questions at a time. Here goes.

  • Check the battery. Is it still there? (Valid question with no evidence of power)
  • Are the terminal clamps tight?
  • Are the terminals clean and free of corrosion?
  • Are all the belts in place and tight? (pay special attention to alternator)
  • If you have a voltmeter. test the voltage at the battery terminals. It should be +12.5VDC.
Try getting a jump, when the cables are attached does anything light up?
Does it turn over and start?
Does it do anything?

Comment me back with your findings
Mike

Find the small air conditioner relay and replace it. They are available at any auto store and may cost perhaps $15. The switches on the dash could also be not making contact but I doubt it. You may have to get a manual to locate where the relay is located on your vehicle.

When you turn the key front. Listen for the fuel pump to prime. It should sound like a low humming noise that lasts about 3 seconds. If it does then check for spark by pulling one of our sparkplug wires and putting an extra spark plug in it. Place the end of the wire down somewhere safe and crank the motor. If you can't seek spark in the plug, it is most likely your coil failing. So, check fuel pump and fuel pump relays first, then spark. Good Luck.

My 2007 keyless entry remotes have stopped working how can I fix them?

Keyless entry remotes allow you to put down and roll up the windows in your car. You would have to have the power windows feature installed on your keyless remote. --------------------------------------------------------------------------------------

My keyless stopped working last week and now my windows roll up and down on there own when i lock my carand walk away. Now my doors unlock and lock when i drive down the road...then last nite my remote...

ive sen this before and im fairly certain the key fob itself isyour problem.to confirm remove the internal battery from the fob and from any additional ones you may have.if your mysterious window and lock problems stop then you definitely need a new fob.please let me know how you make out.

Same problem with an '03 Golf--remote entry, power windows, and interior lights stopped working. This was easily fixed by replacing fuse #14, (10 amp), located in the driver's side fuse block.
