In today’s fast-paced world, convenience is everything. Keyless entry systems have transformed the way we interact with our vehicles, offering both ease and enhanced security. Gone are the days of fumbling with traditional keys in the rain or dark. Now, a simple press of a button or even just walking away from your car can ensure it’s locked and secure. However, with all technological advances, keyless systems can sometimes be a little confusing, especially if you’re new to them or switching from a manual locking system. At Pavlock Auto Locksmiths, we’ve helped countless drivers in Chesterfield and beyond understand their keyless systems better—and we’re here to help you do the same.
As a trusted auto locksmith in Chesterfield, we often receive calls from people unsure if their vehicle is locked properly or confused about how their keyless system works. The reality is, every manufacturer has slightly different mechanisms, and depending on whether you’re using passive entry, a fob with buttons, or a proximity sensor, your approach may vary. What doesn’t change, however, is the importance of understanding how your specific system functions to ensure your vehicle is secure at all times.
Understanding What Keyless Entry Really Means
Before diving into how to lock a car with keyless entry, it’s helpful to understand what the term actually means. Keyless entry typically refers to a system that allows you to lock and unlock your car doors without physically inserting a key into the lock. Some systems are basic and rely on a fob with buttons, while more advanced versions use proximity sensors that detect when the key is near the vehicle. These advanced versions often allow for “walk-away locking” where the car locks itself once the fob is no longer detected nearby.
The system communicates wirelessly between your car and the fob. When the fob is within range, the car’s system recognises it and enables locking or unlocking. For some vehicles, simply pressing a button on the door handle is enough to activate the lock, provided the fob is within range—usually in your pocket or handbag.
Locking the Car with a Key Fob
For most vehicles with keyless entry, the most straightforward way to lock your car is by pressing the lock button on your key fob. This is often marked with a padlock symbol or simply labelled “lock.” When you press the button, your car should make an audible sound—typically a beep—or flash the hazard lights to confirm it’s locked. You might also hear the click of the door locks engaging.
It’s important to double-check that your car is locked properly, especially in busy areas or overnight. Many vehicles offer a double-locking feature, which means pressing the lock button twice disables the interior door handles, adding an extra layer of security.
Using Proximity-Based Locking
Some newer vehicles have taken things a step further by allowing you to lock your car simply by walking away from it. This system is known as passive keyless entry or walk-away auto-lock. As long as you have the key fob with you, the car will detect when it’s out of range and automatically lock the doors.
To ensure your vehicle locks correctly using this method, it’s important not to linger too close to the car after shutting the doors. If the fob is still within the vehicle’s detection range, the system may not engage the locks. You’ll typically hear a confirmation beep or see the hazard lights flash once the locking process is complete.

Locking the Car Using the Door Handle Button
Another common method seen in many keyless vehicles is the use of a small button on the door handle itself. This feature allows you to lock the vehicle simply by pressing the button when the key fob is within range. It’s a very handy function, especially when your hands are full or you want to lock the car quickly without pulling the fob from your pocket.
However, it’s worth noting that this system varies across different car manufacturers. In some vehicles, only the driver’s side door will lock with this method unless you’ve adjusted the settings to allow all doors to lock simultaneously. Familiarising yourself with your car’s manual can help avoid confusion.
Common Mistakes When Locking Keyless Cars
One of the most common issues we encounter at Pavlock Auto Locksmiths is people accidentally leaving their key fob inside the vehicle. Most modern systems are designed to prevent the car from locking if the fob is detected inside, but this isn’t foolproof. In some cases, particularly if the battery in your fob is low or there’s interference from other electronics, the system may fail to detect the fob accurately.
Additionally, some vehicles allow the boot to be opened separately from the main doors. If you drop the fob into the boot and close it, thinking it’s safely in your bag, your car might still lock depending on its settings—leaving you stranded. That’s why it’s always wise to listen for that confirmation beep or check the lights before walking away.
What to Do If Keyless Entry Fails
Technology is great when it works, but it can be frustrating when it doesn’t. If your keyless entry system isn’t locking the car as it should, the first step is to check the battery in your key fob. A weak or dead battery can lead to all sorts of issues, from intermittent locking to complete system failure.
In such situations, having a backup method to lock your car is essential. Many keyless entry systems include a hidden physical key inside the fob, which can be used in an emergency. Some cars also have a concealed key slot on the driver’s door handle. At Pavlock Auto Locksmiths, we regularly help customers locate and use these hidden features when their electronic systems let them down.
The Importance of Staying Vigilant
Keyless entry might make life easier, but it can also be a target for criminals. Relay theft is a well-known technique where thieves use special devices to boost the signal from your key fob, even when it’s inside your home, to unlock and start your car. To avoid this, always store your keys in a signal-blocking pouch (also known as a Faraday bag) when not in use.
We also advise keeping your car’s software up to date, as manufacturers often release patches to address known vulnerabilities in keyless entry systems. And of course, never rely solely on technology—always check that your car is locked, especially if you’re parked in unfamiliar or high-risk areas.
