Do you frequently utilize the transmitter (the ikey buttons)? The batter will drain a lot quicker as a result.


After two years, the key fob for my 2016 Murano indicated a low battery and was replaced. When the same low battery alert appeared two months later and my car was being serviced at the dealership, the technician offered to change the battery. He thought perhaps I had a bad battery. Three months later, the low battery notification has returned. My battery has had to be changed twice in the past five months, and it now needs to be replaced once more. Has anyone encountered this issue and found a solution? In other makes and models of cars, the majority of individuals claim that their battery lasts at least three years. Even though my keyfob is still under warranty, I know Nissan will throw a fit if I ask them to replace it.

Check to determine if the spare key’s battery may be replaced to extend its life. If it does, the original key is broken or shorted in some other way. If both of them drain equally quickly, you may want to consider where you are keeping them. Are they in your pockets, bags, or clothing, where other objects may push against the buttons while you are away from the car?

Other Techniques For Car Unlocking

Still concerned about getting stuck somewhere with a broken key fob? Here are a few alternative ways to start your car if your key fob dies:

  • Remotely enter the vehicle. Use the app on your phone to unlock your car if it has one. Most car manufacturers now offer an app, which was formerly mostly reserved for expensive vehicles. You may open the doors from your phone with the FordPass Connect app, myChevrolet mobile app, MyMazda app, and Toyota app, among others. These apps must be configured before your key fob breaks, and some remote services have monthly fees.
  • Draw nearer. Your key fob’s battery might only be low, not dead, if it doesn’t function from the same range as it typically does. If you get closer to your automobile in this situation, it might unlock. Press the unlock button on your key fob while placing it directly against the door handle.
  • Make a roadside assistance call. Call for assistance if all else fails. Verify if roadside help is covered by your insurance before you run into trouble, then save the number to your phone. Keep a backup copy in your wallet or purse in case your phone dies (or gets locked in the car!).

Deal Diva: Easy ways to care for automobile key fob technology to extend its lifespan

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 press the lock or unlock button on the remote numerous times before it locks or unlocks, it 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) does send a signal continuously, so it drains the battery in the key fob and its causing an excessive drainage on the battery of the automobile,” noted Freeman. “A computer is identifying that signal saying I’m ready to start.”

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.

“In most situations, the owners’ manual will clear that up for you, or practically any auto repair facility can replace that battery,” Freeman continued.

  • The buttons are stationary.
  • The Key is clearly damaged.

A damaged key can be replaced with a new car key. The key fob can be reprogrammed with assistance from the Colorado Springs Locksmith specialists.

  • No spare remotes operate.
  • car remote completely quits functioning
