How long should the battery in a VW key last?

WMBF – MYRTLE BEACH, SC A key fob is used by millions of drivers to lock and unlock their vehicles.

Keyless entry is a fantastic feature, but you can only benefit from it if you keep the technology up to date.

The little things in life can often mean the most, such as not having to search through your purse for your keys or using your key fob to raise and unlock the back doors so you can load groceries.

But what occurs if the fob breaks down? The key fobs for your car require maintenance just like the vehicle itself does.

When anything breaks down, Gary Freeman, owner of C & G Auto in Myrtle Beach, advised against replacing it right away.

“A replacement fob can be pricey; they can cost several hundred dollars, and once you have a replacement fob, they need to be programmed,” said Freeman.

He advises checking the battery as your first action. If you have to push the remote lock or unlock multiple times before it finally locks or unlocks, that could be a sign that the battery is starting to lose power, according to Freeman.

According to his calculations, the keyless entry remote can be safely stored or hung up anywhere beyond the six to ten feet from which the automobile computer system can read the fob.

According to Freeman, the battery life for the majority of automotive key fobs is three to four years with regular use. Additionally, he claims that the battery life of your fob may be impacted by where you keep it. Freeman advises against hanging the fob near the car or leaving it in the car overnight.

It (the key fob) sends signals continuously, which drains the battery in the key fob and causes an excessive drain on the battery of the car since a computer recognizes that signal as indicating that I’m ready to start, according to Freeman.

According to Freeman, if the key fob malfunctions, the automobile frequently won’t start because the computer system won’t acknowledge that the key fob is present in the vehicle.

The owners’ manual will typically answer any questions you have about it, and almost any auto repair shop can replace that battery, said Freeman.

Are there standard VW keys?

Simple no is the response. Since 1995, an immobilizer system has been installed in every Volkswagen vehicle, preventing the vehicle from being started without the proper key. The immobiliser is turned off by the transponder chip in the key’s head. Early VW vehicles were equipped with a separate immobilizer box, while later versionsthose made after 1999had the device integrated into the dashboard.

With the use of a specialized key reader, the locks on all VW models may be read, allowing a new key to be cut to the correct code without removing the lock. The unique code is then programmed to match the vehicle after the correct transponder for the vehicle is inserted into the key.

This technique is comparatively simple for VW cars made between 1995 and 2006. For vehicles made after 2006, a more secure technology is employed in which the transponder is pre-coded. Because each transponder chip is specific to each car, security is increased. However, because the VW’s coded information isn’t easily accessible, this also makes the procedure of replacement keys considerably more difficult for auto locksmiths. Instead, this encoded data is recorded in a file that matches the chassis number of the vehicle.

Normally, you would need to get in touch with the VW manufacturer to have a new key made with a transponder chip that has been coded, which would then need to be shipped to your local dealership. This is a drawn-out process that might take up to 7 days, not to mention the exorbitant charges.

Will a dead key fob prevent a car from starting?

If your key fob isn’t detected inside the car, the keyless entry system won’t start the engine. The system probably won’t be able to tell when the key fob is inside the car if it has a dead battery, which will prevent the engine from starting. By pressing down while placing the fob on the start engine button, you can get past this problem. Even though this should enable your engine to start, it is still beneficial to change the fob batteries whenever you have the opportunity.

What happens if your key fob breaks?

  • On your key fob’s back, search for a little sliding button. You can slide the key fob cover off or click a button to do so. To get it to release, you might need to use your fingernail and a little force.

Now that you’re inside, here’s how to start the car with a dead key fob:

  • Close the key fob after inserting the mechanical key once more.
  • Some vehicles have a secret key fob slot that can be used to start the engine. For instance, the backup slot is located inside the cup holder in some Ford models. Your fob will fit perfectly in the slot. Use the push button start as usual after inserting the dead key fob into the holder.
  • Press the START button with the key fob. Instead than pressing the button with your finger as usual, push the key fob against it. Many manufacturers utilize this backup device to make sure the car can start even if the key fob is dead.
  • Check the steering column for a physical key slot if neither of these approaches succeeds (some Mazda models have this feature). To start the car, place the mechanical key within the keyhole.

Should I reprogramme my key fob after changing the battery?

A remote key fob needs to be associated with your vehicle particularly in order to be secure.

This stops people who drive the same make and model of automobile as you from using their remote to access your car. You’ll need to reprogram the fob if changing the batteries has erased this connection or if it was somehow disrupted in order for it to once again recognize your automobile.

Your key fob can typically be reconfigured by following this typical procedure:

Instead of starting and then returning to the locked position, turn the key into the run position. Repeat this multiple times.

You’ll typically hear a chime or other sound when you’ve cycled the key enough times. At that point, you can push the lock or unlock button on your key fob to hear another chime.
