How to Increase Key Fob Range

If your car key fob has a weak signal or doesn’t work from very far away, there are a few things you can do to try and increase the range. First, check the battery to make sure it’s not dead or low. If the battery is good, then clean the key fob’s contact points with a cotton swab dipped in rubbing alcohol.

You can also try reprogramming the key fob according to your car’s instructions. If none of these things work, you may need to replace the key fob entirely.

  • One thing you can do is to replace the battery with a new one
  • You can also try moving the antenna around on the key fob until you find the optimal position for signal strength
  • Another thing you can do is to use a signal booster, which will amplify the signal from your key fob and help extend its range

How to Increase the Range of your Key Fob

Key Fob Range Extender

If you have a car with a keyless entry system, you may have experienced the frustration of not being able to unlock your doors or trunk when you’re out of range. A key fob range extender can solve this problem by amplifying the signal from your key fob and extending its range. There are a few different types of key fob range extenders on the market, but they all work in basically the same way.

Most consist of two parts: a small transmitter that attaches to your key fob, and a receiver that plugs into your car’s cigarette lighter socket. When you press the button on your key fob, the transmitter sends a signal to the receiver, which then amplify it and send it to your car’s antenna. Key fob range extenders are relatively inexpensive and easy to use, so they’re definitely worth considering if you’ve ever been frustrated by your car’s keyless entry system.

How Can I Increase the Range of My Car Keys?

If your car keys are not working as far as they used to, there are a few things you can do to try and increase the range. First, check the batteries in both the key fob and the receiver. If they need to be replaced, that should help with the issue.

If that doesn’t work, there are a few other potential solutions. One is to use a key fob signal booster. This device amplifies the signal from the key fob so that it can reach further.

Another option is to replace the antenna on the receiver unit in your car. A third possibility is to add an RF repeater system, which will extend the range of any wireless signal, including your car key signal. All of these solutions require some technical knowledge and should be done by a professional if you’re not comfortable doing them yourself.

But if you’re willing to put in some effort, they could help increase the range of your car keys so that you don’t have to worry about being too far away from your vehicle when you want to unlock it or start it up.

Why is My Key Fob Range So Short?

A key fob, also known as a keyless entry or remote, is a small device that typically attaches to your keychain. It allows you to unlock your car doors and trunk, start the engine, and even activate the panic alarm – all without having to insert a key into the ignition. Many newer cars also allow you to keep the fob in your pocket and simply push a button on the door handle to enter the vehicle.

While this convenience is certainly appreciated by most drivers, there is one downside – shortened range. In other words, the further away you are from your car, the less likely it is that your key fob will work. So why is this?

Let’s take a look at some of the reasons why your key fob range might be shorter than expected. Interference from Other Devices: One of the most common causes of shortened key fob range is interference from other devices. This includes things like cell phones, microwaves, Bluetooth devices, and even garage door openers.

If you live in an area with lots of electronic devices or have one of these devices near your car keys, it could be interfering with the signal between your keys and your car. Low Battery: Another common reason for shortened key fob range is simply because the battery is low. Most modern key fobs use lithium ion batteries which can last up to 5 years before needing to be replaced.

However, if you’ve had yours for awhile or use it frequently (like if you have a long commute), it might need to be replaced sooner. You can usually tell if this is the case if your keys feel lighter than usual or if they stop working entirely until you put them back in close proximity to your vehicle (within 1-2 feet). Out-of-Date Technology: While many newer cars come equipped with advanced “rolling code” technology that changes each time you press your remote’s button (making it harder for thieves to steal signals), not all vehicles have this feature yet.

If yours doesn’t uses rolling code technology and someone happens to get ahold of your signal while you’re pressing the button far away from your car, they could easily clone it and gain access to your vehicle without any trouble at all! So there are just a few reasons why your once trusty key fob might have shorter range than usual these days.

How Do I Increase My Factory Remote Start Range?

If you’re looking to increase the range of your factory remote start, there are a few things you can do. First, make sure the antenna on your vehicle is in good shape and positioned correctly. If you have an aftermarket alarm system, check the settings to see if the range can be increased.

You can also try using a signal booster, which will amplify the signal from your remote and extend its range. Finally, keep in mind that obstacles like metal objects or thick walls can impede the signal from your remote, so try to avoid starting your car in areas where there are lots of obstacles.

How Far is the Range on a Key Fob?

Most key fobs have a range of about 100 feet, give or take. That said, there are a few things that can affect the range of your key fob, including: -The type of key fob you have: Some key fobs use radio frequencies while others use infrared (IR) signals.

Radio frequencies have a longer range than IR signals, so if you have a RF key fob, it will likely have a longer range than an IR key fob. -The condition of your battery: A fresh battery will usually provide better performance than an old or dying one. If your key fob’s range has been gradually declining, it might be time to replace the battery.

-Interference from other electronic devices: If you live in an area with lots of electronic interference (like near a power plant or airport), that interference can play havoc with your key fob’s signal and reduce its effective range.


If you have a key fob for your car, you may have noticed that the range is not always ideal. There are a few things that you can do to try and increase the range of your key fob, so that you don’t have to be right next to your car to unlock it. First, check the battery in your key fob.

If it’s running low, it will definitely affect the range. Replace the battery if necessary. Second, clean the contacts on both your key fob and car.

Over time, these can get dirty and oxidized, which affects the connection between them. Third, if you have a metal key ring attached to your key fob, try removing it. Sometimes the metal can interfere with signal strength.

Fourth, move any other electronic devices out of your pocket before trying to unlock your car door. Phones or other keys with RFID chips can also interfere with signal strength. Finally, if all else fails, there are aftermarket products available that extend the range of most types of key fobs.

These typically come in the form of a small device that attaches to your keys and relays signals from a distance back to your car door lock receiver unit.
