Question about 2005 Nissan Sentra

1 Answer

My keyless entry stopped working.

A few months ago, my fob stopped working. I thought it was a simple fix by replacing the battery. I was sitting in the drivers seat replacing the battery in the fob and put it back together. Pushed the lock button and it worked! I drove back to work right after this and it wasn't working again. A couple of weeks later, I went out of town. We stopped for a bite to eat and I thought, "What the heck, let me just try the fob." It worked!! Then, later that day, it stopped again. I have given up even trying anymore and think it may be the sensor itself. I have little knowledge about this type of stuff and don't want to spend a fortune if it can be an easy fix.

    The problem is most likely the anti-theft module is not cheap fix, because it is a Japanese car look to spend 4 or 5 times as much for the part as a typical american car.

Disassemble the FOB and clean board with electric degreaser like ZEP I.D. red. Make sure the rubber pads are directly over the contacts before re-assemble.

On my 2006 Nissan Altima the Key fob stopped


Take the fob off the key ring and leave at home. Does it still do funky things? If not - it is the fob and first vote is to replace the battery inside - typically a lithium cell. Or the fob itself. If still acting up with the fob away, pull the fuse for the keyless entry, count to 30 and put back. Another less likely cause is the relay - under the hood - marked Keyless entry. If you need to replace the fob, there are instructions for Nissan on numerous sites including below, I have replaced a 2003 and reprogrammed the car to recognize. 2006 Nissan Altima Keyless Entry Remote Programming Instructions...

If your keyless entry remote has never worked it either needs to be programmed to the vehicle or it is the incorrect remote part number for they vehicle. First step is to call your local dealership, ask for service, then verify your vehicle came equipped with the keyless entry option and verify the key fob part number. When calling the dealer have your vin# handy, they will need that. Once you have verified your vehicle has keyless entry option and you have the correct keyless entry remote part number then find a locksmith to program the remote to your vehicle. We suggest a locksmith because they are usually more affordable than the dealer and they come to you.

If your keyless entry remote has worked before and it just stopped working, here are a few tips to try to get it working again:

1) Change the battery
Batteries don't last forever, you'll be surprised how often it's just a dead battery! Search our YouTube channel on how to change a key fob 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 purchase a key fob or give us a call at 402-671-5100.

2001 Chevy cavalier Z24 keyless entry not working.


You should have it scaned to see if you have any codes. It has a RCDLR (remote control door lock reciever) this is the module that recieves the signal from the fobs. If it has a problem then the system will not work. If it has to be replaced then a dealer will have to program it for you. Good Luck

Keyless entry


If you do not currently have a fob that works you will have to take it to the dealer and they will use a DRBIII scan tool to re-program it. Is the battery good in the transmitter?

2004 Chevy Impala Keyless Entry System Stopped Working


Do the power door locks work when used with the switches located on the interior doors? If so, then it sounds to me like you got a problem with your key fob. Probably a dead battery in it.

Keyless Entry Key Doesn't Work


Regarding the remote transmitter issue: Take the remote transmitter to your Toyota dealer. Ask them to test your transmitter with their hand-held RF detector. All Toyota dealers are required to have one of these devices. The RF detector will test the remote to see if it is indeed transmitting the proper RF out of the transmitter, and the strength of the RF signal. If there is no signal, the remote has failed (unfortunatly common), and the remote will need to be replaced and reprogrammed to the vehicle. I do this quite regularly, and rarely do I tell customers taht they need to spend 800 dollars for such a simple diagnosis/fix. The keyless system is very reliable. I rarely change the ECU for the keyless, unless somebody somehow gets the ECU wet, then it def needs replaced. Hope this helps.

I had the same exact problem and fixed it by disconnecting the battery for 5 minutes. I was also having a problem with the A/C compressor not kicking in and after the battery disconnect it is working fine.
