- Some insurance companies offer discounts to vehicle owners who utilize deadlocking, recognizing its effectiveness in preventing theft and damage.
What is Deadlocking and How Does it Work?
A deadlock is an advanced security feature that completely disables a vehicle’s door locking mechanisms, preventing the doors from being opened from both the inside and the outside once activated. It’s essentially a second level of locking that goes beyond standard central locking.
When a car is deadlocked, pulling the interior door handles or pressing the unlock buttons will have no effect. The doors remain locked, even if a thief manages to break a window and reach inside. This is achieved through a separate set of locking mechanisms that are engaged when the deadlock is activated. These mechanisms typically involve additional bolts or levers that secure the door to the frame, independent of the regular locks. The specifics can vary depending on the vehicle’s make and model. Some use electronic actuators, while others rely on mechanical linkages.
Key Takeaway: Deadlocking provides an extra layer of security by preventing anyone from opening the doors from the inside, even if they gain access to the car’s interior.
How to Activate Deadlocking in Most Cars?
In many vehicles, deadlocking is activated by pressing the lock button on the key fob twice in rapid succession. Some cars may use a different method, such as a separate button on the key fob or a switch inside the car.
The exact sequence can vary depending on the make and model. For example, some European cars, like certain BMW models, activate the deadlock with a single press of the lock button. Others, like some Ford models, require a double press within three seconds. According to a study by the National Insurance Crime Bureau (NICB), understanding your vehicle’s specific locking mechanism is crucial for effective security.
Tip: Always consult your vehicle’s owner manual for the precise method of activating the deadlock feature.
How to Deactivate Deadlocking?
Deadlocking is typically deactivated by pressing the unlock button on the key fob. This disengages the additional locking mechanisms, allowing the doors to be opened normally from both the inside and outside.
It’s important to note that in some vehicles, using the physical key in the door lock may not deactivate the deadlock. This is an added security measure to prevent thieves from using tools to manipulate the lock cylinder. In most cases, only the key fob or a designated interior button will deactivate the deadlock.
Why is Deadlocking Important for Car Security?
Deadlocking significantly enhances car security by making it much more difficult for thieves to break into a vehicle and steal it or its contents. It serves as a strong deterrent against common theft methods.
Without deadlocking, thieves can use tools to reach through a partially open window or a smashed window to unlock the doors from the inside. Deadlocking renders this tactic useless. Even if they gain entry, they cannot open the doors to remove large items or drive the car away. A report by the FBI indicates that opportunistic theft often relies on easy access, which deadlocking effectively prevents.
What are the Benefits of Using Deadlocking?
- Enhanced Security: Deadlocking provides an extra layer of protection against theft.
- Deterrent Effect: The knowledge that a car is deadlocked can deter thieves from even attempting a break-in.
- Peace of Mind: Knowing your car is more secure can provide peace of mind, especially when parking in high-risk areas.
- Insurance Benefits: Some insurance companies offer discounts for vehicles equipped with deadlocking.
Are There Any Drawbacks to Deadlocking?
While deadlocking offers significant security benefits, it also poses potential safety risks if not used properly. The primary concern is the possibility of trapping occupants inside the vehicle in an emergency.
If a car is deadlocked with people inside, they will not be able to open the doors from the inside to escape in case of an accident, fire, or other emergency. This is particularly dangerous for children or pets who may not understand how to deactivate the deadlock. As highlighted by the Royal Automobile Club (RAC), it’s crucial to be aware of this risk before leaving anyone inside a parked car.
Key Takeaway: Deadlocking should never be activated when people or pets are inside the vehicle.
What Types of Cars Have Deadlocking?
Deadlocking is a common feature in many modern vehicles, particularly those manufactured in Europe and increasingly in other regions. It is often found in higher-end models but is also becoming more prevalent in mid-range and even some economy cars.
Brands known to use deadlocking include, but are not limited to:
- BMW
- Mercedes-Benz
- Audi
- Volkswagen
- Ford (European models)
- Kia
- Tesla
Tip: If unsure, you can test your car by rolling down a window, locking the car with the remote, waiting a minute, and then trying to open the door from the inside using the handle. If it doesn’t open, your car likely has a deadlocking feature.
How Can I Tell if My Car Has Deadlocking?
The most reliable way to determine if your car has deadlocking is to consult the owner’s manual. It will provide detailed information about your vehicle’s security features, including whether it has deadlocking and how to activate and deactivate it.
Best Practices for Using Deadlocking Safely and Effectively
- Never Deadlock with Occupants Inside: This is the most important safety rule. Always ensure everyone has exited the vehicle before activating the deadlock.
- Educate Passengers: If your car has deadlocking, inform your passengers about it and how it works. Show them how to deactivate it from the inside if there’s an emergency and they are alone in the vehicle.
- Use Sparingly in High-Risk Areas: While deadlocking can deter theft, it’s best used when parking in areas known for high rates of car crime or when leaving your vehicle unattended for extended periods.
- Consider Alternatives: In situations where you need to leave the car locked but accessible from the inside (e.g., quick errands), consider using standard locking instead of deadlocking.
How to Use Deadlocking in Conjunction with Other Security Measures
Deadlocking is most effective when used as part of a comprehensive vehicle security strategy. It should be combined with other measures for maximum protection.
Here’s how to integrate deadlocking with other security features:
- Alarm System: Ensure your car alarm is activated when you deadlock the vehicle. This provides an audible deterrent and can alert you to any attempted break-in.
- Steering Wheel Lock: A visible steering wheel lock can deter thieves, even if they manage to bypass the deadlock.
- Immobilizer: Most modern cars have engine immobilizers that prevent the car from starting without the correct key. This works in conjunction with deadlocking to prevent the vehicle from being driven away.
- Tracking Device: Consider installing a GPS tracking device. If your car is stolen, this can help the police recover it quickly.
Key Takeaway: Combining deadlocking with other security measures creates a multi-layered defense system that significantly reduces the risk of theft.
What are the Alternatives to Deadlocking for Car Security?
While deadlocking is a powerful security feature, it’s not the only option for protecting your vehicle. Several alternatives can be used alone or in combination with deadlocking.
- Standard Central Locking: This locks all doors but still allows them to be opened from the inside.
- Steering Wheel Lock: A physical lock that prevents the steering wheel from turning.
- Gear Shift Lock: A device that locks the gear shift in the “Park” position.
- Wheel Clamps: A large, visible clamp that immobilizes one of the car’s wheels.
- Kill Switch: A hidden switch that disables the ignition or fuel system.
- Etching: Permanently marking your car’s windows and other parts with the Vehicle Identification Number (VIN) can deter thieves, as it makes the parts harder to sell.
Tip: Choose security measures that best suit your needs, budget, and risk level. For example, if you live in a low-crime area, a steering wheel lock might be sufficient. If you park in a high-risk area, you might want to use deadlocking in combination with other measures.
How Do I Choose the Right Security Measures for My Car and Situation?
Selecting the appropriate security measures depends on several factors, including your car’s make and model, where you park, and your personal risk tolerance. Consider the following:
- Vehicle Value: High-value vehicles are more attractive to thieves and may require more robust security measures, including deadlocking.
- Location: If you frequently park in areas with high crime rates, you’ll need stronger security than if you park in a secure garage or a low-crime neighborhood.
- Insurance Requirements: Some insurance policies may require specific security measures, such as an immobilizer or alarm system.
- Personal Comfort Level: Choose security measures that you’re comfortable using regularly. There’s no point in having a complex system if you’re not going to use it consistently.
Key Takeaway: Assess your individual circumstances and choose a combination of security measures that provide adequate protection without being overly burdensome.
