how to upgrade your car’s locking system

Last Updated on February 11, 2025 by Alan Weir

As a seasoned car locksmith, I’m here to unravel the intricacies of car security, helping you understand how to upgrade your car’s locking system effectively. Whether you’re driving a classic beauty or a modern marvel, enhancing your vehicle’s security is paramount. It not only keeps your prized machine safe but also gives you peace of mind while you navigate the bustling streets. Let’s journey through the fantastic world of automotive security systems and discover how you can fortify your vehicle effortlessly.

Understanding the Basics of Car Locking Systems

Before we delve into the upgrading process, it’s essential to grasp how modern car locking systems function. Most vehicles come equipped with one of two types of locking mechanisms:

  1. Traditional Mechanical Locks: These involve a simple key insert and rotation to lock and unlock. Although they may seem antiquated, many older models still utilize these systems.

  2. Electronic Locking Systems: Newer models feature keyless entry and start systems, which use remote controls or smartphone apps to operate locks. These systems are more convenient but can also be vulnerable to hacking if not properly secured.

Whatever system your car employs, upgrading your locking method can significantly strengthen your vehicle’s defences.

Assess Your Current Locking System

Before any upgrades, it’s prudent to assess your current system. Spend a little time evaluating the vulnerabilities inherent in your setup. Here are some essential questions to consider:

  • Are the keys conventional or equipped with transponders?
  • Do you have a spare key, and is it easily accessible to you?
  • How old is your current locking system?

Understanding these elements will empower you to make informed decisions about which upgrades suit your needs best.

Upgrading to Keyless Entry and Start Systems

Keyless entry and start systems have surged in popularity in recent years, primarily because they offer unmatched convenience. No more fumbling for keys in bags or pockets! These systems operate using proximity sensors and RFID technology, allowing you to unlock your car just by being nearby.

Considerations for Keyless Systems

While keyless systems provide convenience, they also come with potential vulnerabilities. To mitigate risks, consider:

  • Quality of the Key Fob: Avoid purchasing flimsy or unknown-brand key fobs that might compromise your security. Instead, opt for OEM (Original Equipment Manufacturer) key fobs that are specifically designed for your vehicle.

  • Signal Blocking Technology: Thieves often use relay attacks to intercept signals between your key fob and your car. To counteract this, consider acquiring a Faraday pouch, which blocks unwanted signals to your transponder.

Installation

Installing a keyless entry system should be done by a professional if you’re unfamiliar with wiring or electronics. However, if you’re feeling brave and want to attempt a DIY upgrade, you can follow this step-by-step instructional guide. Be aware that messing with your car’s electronics can sometimes lead to larger headaches.

Installing a Remote Start System

Imagine a chilly winter morning: you step outside, and instead of shivering in the cold, your car is already warmed up. A remote start system can grant you that comfort.

Benefits of Remote Start Systems

  • Convenience: Start your vehicle from the comfort of your home.
  • Safety: No need to exhaustively scrape ice or snow off your vehicle; just start and go.
  • Added Security: Many remote start systems come with additional alarm features that provide alerts if someone attempts to enter your car without your permission.

Customising Your Remote Start System

When choosing a remote start system, select one compatible with your make and model. Websites like Crutchfield provide useful reviews and recommendations tailored to specific vehicles. It’s vital to ensure that any modification you make does not void your warranty with the manufacturer.

Installation Process

As with the keyless entry, professional installation is recommended to keep your warranty intact. If you choose the DIY route, here’s a quick overview of the installation process:

  1. Connect the wiring harness to your vehicle’s ignition circuit.
  2. Set up the antenna and control module.
  3. Fine-tune the settings to ensure that your vehicle responds to the remote.

Make sure you consult the installation manual specific to the kit you’ve purchased for detailed steps.

Amplifying Lock Security with Deadbolts

For those who want an additional layer of security, consider installing deadlocks. Unlike standard locks, deadlocks offer a more robust locking mechanism, making it difficult for unauthorised individuals to access your vehicle.

How Deadlocks Work

Deadlocks work by employing a bolt that secures your car’s doors from both sides. They can only be activated using a key or remote, meaning that even if a thief manages to tamper with your standard lock, the deadlock remains secured.

Installation Tips

Installing a deadlock requires some handiwork. If you’re handy with tools, here’s a brief breakdown of the process:

  1. Choose a reputable deadlock kit suitable for your car model.
  2. Using a drill, create the necessary holes in your door frame and skin.
  3. Secure the deadlock mechanism and install the locking pins.

If this sounds too complicated, feel free to engage a professional to avoid potentially damaging your car.

Using Advanced Security Technologies

GPS Tracking Systems

Adding a GPS tracking system can significantly deter theft. In the unfortunate event your car gets stolen, these systems allow for swift recovery.

Key Features

  • Real-time Tracking: Monitor your vehicle’s location via a mobile app.
  • Geofencing Alerts: Set up a virtual perimeter and receive notifications if your car crosses it.

Consider options like Tracki or other reputable brands that offer reliable GPS tracking solutions.

Steering Wheel Locks

A simple yet effective solution is to invest in a steering wheel lock. It’s a physical deterrent that makes your car difficult to drive away with, acting as a visible deterrent.

When securing your vehicle, don’t underestimate the power of visual security measures. Many potential thieves are deterred simply by the sight of a steering wheel lock, preferring easier targets.

Insurance Policies

While upgrading your locking system, it’s wise to reflect on your car insurance policies. Specific upgrades can sometimes lead to lower premiums or comprehensive coverage options. Ensure you inform your insurance provider about any enhancements you’ve made.

Maintenance and Staying Updated

As technology evolves, so do methods for enhancing your vehicle’s security. Regularly updating your locking systems, and keeping abreast of industry trends is vital to ensuring your car remains secure. Join forums focused on automotive updates or follow reliable blogs that share tips on protecting your vehicle.

Regular Checks

Regular maintenance checks on your car’s locking mechanisms are prudent. Ensuring that everything is functioning well can prevent lock failures that might leave you vulnerable. Periodically, you should:

  • Test electronic locks from your key fob.
  • Check for any unusual wear or tear.
  • Replace any weak batteries in your key fob or remote start.

By being proactive, you maintain the integrity of your car’s locking system and ensure maximum security at all times.

The Savvy Car Owner’s Takeaway

Upgrading your car’s locking system isn’t just about convenience; it is an investment into the safety of your vehicle and peace of mind. You don’t have to break the bank to secure your car, but being informed and proactive about upgrades will pay dividends in the long run. As an expert car locksmith, I’m here to guide you through understanding and implementing the best strategies to protect your beloved car. So roll up your sleeves and get ready to enhance your vehicle’s security like a pro!
