5 Ways to Identify Keyless Entry in Your Used Car

So you just bought a used car and you’re not entirely sure if it has keyless entry or not. This is a common problem that many car owners face. Keyless entry systems have become increasingly popular in recent years, and they can make unlocking your car much easier and more convenient than using traditional keys. In this article, we will go over five ways to identify keyless entry in your used car.

5 Ways to Identify Keyless Entry in Your Used Car

1. Check the Owner’s Manual

The owner’s manual is a great resource to use when trying to identify keyless entry in your used car. The manual will usually have a section that explains how to use the keyless entry system, and it may also have a diagram or picture that shows what the keyless entry system looks like. If you don’t have a physical copy of the manual, you can usually find a digital version online. Search for your vehicle’s make and model and add “owner’s manual” to the search terms.

Tip: If you are buying a car from a dealership or private seller, ask them for the owner’s manual before you make the purchase.

2. Look for a Key Fob

A key fob is a small remote that allows you to lock and unlock your car doors without using the traditional key. Key fobs are a standard feature on most keyless entry systems, so if your used car has a key fob included with the keys, there’s a good chance that it has keyless entry.

Sub-Tip: Make sure to check the key fob for any damages or signs of wear and tear before purchasing the car. Replacement key fobs can be expensive.

3. Look for a Button on the Door Handle

Some keyless entry systems have a button on the door handle that you can press to unlock the doors. This is called a passive entry system. Sometimes, the button will be a different color or shape than the rest of the door handle, so it’s easy to identify. This feature may not be available on every make and model of car, so if you don’t see a button on the door handle, don’t worry, it doesn’t automatically mean your car doesn’t have keyless entry.

Sub-Tip: Some cars may have a button on the trunk as well. This allows you to open the trunk without using the traditional key.

4. Look for a Start/Stop Button

Some keyless entry systems also have a start/stop button located in the car’s interior. This means you can start the car without using a traditional key. The start/stop button may be located on the dashboard or center console. This feature is usually only available on higher-end models.

Sub-Tip: Some keyless entry systems allow you to start the car remotely using a smartphone app.

5. Check the VIN

The VIN (Vehicle Identification Number) is a unique 17-digit code that identifies your car. This code can be found in several places throughout the car, including the driver’s side dashboard, the door frame, and the engine block. You can use the VIN to look up the car’s features and specifications, including whether or not it has keyless entry. There are several online databases that allow you to search for a car’s features based on its VIN.

Sub-Tip: If you’re having trouble finding the VIN, ask a mechanic or dealership to help you locate it.


Keyless entry systems can make your life easier, but it can be difficult to identify if a used car has one or not. By following these five tips, you can easily identify whether or not your used car has keyless entry. Remember to check the owner’s manual, look for a key fob, button on the door handle, start/stop button, and the VIN. By using these methods, you’ll be able to enjoy the convenience of keyless entry in your used car.


How do I know if my used car has keyless entry?

You can tell if your car has keyless entry by checking for a few things. First, look for a small button on the driver’s door handle that allows you to unlock or lock the car without using a key. Next, check your key fob – if it has buttons that allow you to unlock or lock the car, or start it remotely, then the car likely has keyless entry. Lastly, check the owner’s manual or call the manufacturer to confirm whether or not the car has keyless entry.

Can I add keyless entry to my used car if it doesn’t already have it?

Yes, there are aftermarket keyless entry systems that can be installed into your car if it doesn’t already have it. However, it can be costly and may require professional installation. It’s important to do your research and choose a reputable brand and installer.

Are there any downsides to keyless entry?

One downside to keyless entry is that it can be more susceptible to hacking or theft. Thieves can use devices to intercept the signal between the key fob and the car, allowing them to unlock and steal the car. Additionally, if the car’s battery dies or the key fob is lost or damaged, it can be difficult or expensive to replace.
