Running errands or stepping out of your Lexus momentarily while leaving the engine running can be convenient, especially when you’re in a rush. However, ensuring the security of your vehicle is of utmost importance. Fortunately, Lexus provides a simple and effective method to lock your vehicle while the engine is running.
In this guide, we will walk you through the step-by-step process to safely lock your Lexus and protect it from unauthorized access. By following these instructions, you can have peace of mind knowing that your vehicle is secure, even when you’re not inside. So let’s dive in and learn how to lock your Lexus while it’s running.
To lock a Lexus vehicle while it is running, you can follow these steps:
- Ensure that the vehicle is in a safe and stationary position. It’s important to be aware of your surroundings and make sure there are no obstacles or hazards nearby.
- Locate the key fob or smart key that came with your Lexus. The key fob typically has lock and unlock buttons.
- Press the lock button on the key fob once. This should lock all the doors of the vehicle, including the driver’s door.
- If you have a keyless access system, you can lock the vehicle by touching the door handle sensor. Locate the small indentation on the outside of the door handle and place your finger on it. The vehicle should lock.
- Some Lexus models may also have a physical lock button on the driver’s door handle. If your vehicle has this feature, press the lock button to lock the doors.
It’s important to note that leaving a vehicle running and unattended can be risky, as it can be a target for theft or other unauthorized access. Always use caution and assess the situation before leaving your running vehicle.
How to Leave Car Running With Doors Locked
Most people know that you should never leave your car running with the doors unlocked, but did you know that it’s also a good idea to keep your car running while locked? Here are a few reasons why:
1. You’ll stay warmer in the winter.
If you’re waiting for someone in your car and it’s cold outside, keeping the engine running will help keep you warm. Make sure to crack a window though so you don’t get too much carbon monoxide exposure.
2. The battery won’t die as quickly.
If you’re going to be sitting in your car for awhile (like at a drive-thru), keeping the engine running will help keep your battery from dying.
3. Your windows will defrost faster.
In the winter, if your windows are iced over and you need to defrost them quickly, turn on the engine and let it run for awhile.
The heat from the engine will speed up the process. Of course, there are some caveats to this advice.

Can I Lock My Car While It’S Running?
Yes, you can lock your car while it’s running. There are a few different ways to do this, depending on the type of car you have. If your car has an electronic key fob, you can usually lock the doors by pressing a button on the fob.
If your car doesn’t have an electronic key fob, you can usually lock the doors by turning a knob or lever on the inside of the door. Once the doors are locked, no one will be able to open them from the outside.
Does Lexus Have Walk Away Lock?
Yes, Lexus has a walk away lock feature. This feature allows the doors to automatically lock when the vehicle is turned off and the key fob is not in range. This helps to prevent theft and makes it more convenient for the owner.
How Do You Lock Your Car Door While Driving?
If you have an automatic transmission, you can lock your car doors while driving by engaging the child safety locks. To do this, push the button on the driver’s door panel that has a picture of a car with a locked door. This will engage the child safety locks and prevent the backseat passengers from opening the doors while the car is in motion.
If you have a manual transmission, you can also lock your car doors while driving. However, instead of using the child safety locks, you will need to physically lock each door with the key. To do this, insert the key into the keyhole on each door and turn it until you hear a clicking sound.
This will indicate that the door is locked and cannot be opened from the inside.
How Do I Lock My Lexus Keyless?
If you have a keyless entry system on your Lexus, you can lock the doors by pressing and holding the “Lock” button on the door handle. If you want to double-check that the doors are locked, you can do so by pressing the “Lock” button on the remote control or by checking the status lights on the door handles. The red light next to the “Lock” button indicates that the door is locked.
Conclusion
Familiarizing yourself with the specific features of your Lexus model and following the recommended procedures for locking the vehicle while running is essential for maintaining security and peace of mind. By understanding and utilizing the available keyless entry and smart key technology, you can protect your Lexus from unauthorized access and potential theft, enhancing your overall driving experience.
