Changed battery on my key fob and it won't work


What is year--make--model?
The key fob is a transmitter so there has to be a receiver in the vehicle. At the moment, I can't tell if problem with transmitter or receiver? Can you try a different key fob? Where applicable, if key fob needs to be programmed, maybe the info is in your owners manual?

2010 Ford Focus keyless entry quit working


Here are a few things to try and get your Ford Key Fob working again:

1) Change the battery
Batteries don't last forever, you'll be surprised how often it's just a dead battery! Click here for a video on how to open a GM key fob, or search our YouTube channel on how to change a battery for your specific year, make, and model!

2) Wipe the board
The board inside your remote can get a lot more filthy than you think! When the board is dirty it can prohibit the contact to the circuit board when you push down on the button. Simply wiping the circuit board off can make your key fob like new again!

3) Get it checked
Go to your local hardware store like AutoZone or Oreilly's. They usually have a RF frequency tester. This little gadget will let you know if your key fob is sending a signal. If it is, you may need to reprogram your key fob to your vehicle

4) The old car battery reset trick
I know this sounds absurd, but it works sometimes and is worth trying. If you exhausted all of the options above, disconnect both terminals on your car battery for 10 minutes. Then reconnect them and try your key fob. This has worked for many people and I have no idea why. If you do, please comment below to explain.

5) New fob!
It might be time for a new key fob! No need to dread over the expensive costs of a new key fob, at Keyless Entry Remote Fob Inc., you can get a refurbished one for a very affordable price! You won't even be able to tell the difference. Just search your vehicle make, model, and year to find your key fob or give us a call at 402-671-5100.

Fob key wont work just replaced battery in fob and keys wont lock manually either, car has been standing for awhile.


Key fobs can be tricking and even something as simple as changing the battery can cause some issues. The good news is there are a few tricks to try before you panic.

1) The old car battery reset trick
I know this sounds absurd, but it works sometimes and is worth trying. If you exhausted all of the options above, disconnect bot terminals on your car battery for 10 minutes. Then reconnect them and try your key fob. This has worked for many people and I have no idea why. If you do, please comment below to explain.

2) Get it checked
Go to your local hardware store like AutoZone or Oreilly's. They usually have a RF frequency tester. This little gadget will let you know if your key fob is sending a signal. If it is, you may need to reprogram your key fob to your vehicle

3) Make sure the battery in the key fob is installed correctl
Try turning the battery upside down. If you have the positive end on the negative terminal it is not going to work.

Hopefully one of these tips will get the key fob working again. If not you can always purchase a replacement key fob online from

I changed my car battery, now my 2008 Nissan Altima key fob won't work


There is a special procedure involved in keying your fob to your car once the battery has been changed. You must lock and open the door with your key. Turn the ignition to "on"(not start) then push the fob's open and close button, then shut off ignition. This procedure is done everything the key battery is changed. Hope this can help you!
