How Do You Install A Keyless Entry System?

Step 1: Remove the Existing Deadbolt & Knob

Before introducing the advanced security of a keyless entry system, you must remove any existing locks on your door. It involves unscrewing and carefully taking out both the deadbolt hardware and the door knob.

Ensure you have the right tools, typically a screwdriver, to avoid damaging your door. It’s essential to proceed with caution, keeping all parts and screws organized for a smooth process.

Step 2: Measure Your Door’s Backset

The next critical step is to measure your door’s backset—the distance from the edge of the door to the center of the hole where the lock will be installed. This measurement is crucial because it determines the correct positioning of the new keyless entry system.

Most doors have a backset of either 2-3/8 inches or 2-3/4 inches and many keyless entry systems are designed to be adjustable to fit these standard sizes. Accurate measurement ensures that your new system fits perfectly and operates smoothly.

Step 3: Fit the New Deadbolt

With the old lock removed, it’s time to install the new deadbolt. Insert the new deadbolt into the hole on the edge of the door, making sure that the top is facing upwards. Align it properly with the door frame, and secure it in place using the screws provided.

If your door frame has a pre-existing hole, ensure the new deadbolt fits snugly; otherwise, you may need to adjust the size of the hole or use a mounting plate for a secure fit.

Step 4: Set Up Your Entry Code

Follow the setup instructions included with your keyless entry system to program your access code. This process typically involves entering a default code on the keypad, followed by your chosen unique code. Selecting a code that’s easy for you to remember but hard for others to guess is essential.

After setting your code, test it a few times to ensure it’s programmed correctly. Remember, many systems allow you to program multiple codes, offering convenient access for family members or trusted visitors.

Step 5: Attach the New Knob & Strike Plates

Once the deadbolt is in place, attach the new knob or lever on the interior side of the door. Ensure that the locking mechanism aligns correctly with the deadbolt for smooth operation.

Next, secure the strike plates on the door frame, which the deadbolt will latch into when locked. Strike plates must be properly aligned with the deadbolt to ensure the lock functions correctly and provide maximum security.

Step 6: Test Your New Lock

After installation, thoroughly test your new keyless entry system to ensure it’s working properly. Check that the door lock responds correctly to your access code and that the deadbolt fully extends into the strike plate on the door frame, securing the door.

Test the lock several times from both the inside and outside, and if your system includes remote control features or Bluetooth connectivity, verify those functions are operational as well.

How Much Does It Cost To Install A Keyless Entry?

The cost of installing a keyless entry system varies widely, depending on several factors, including the type of system, property size, and the complexity of the installation.

For residential properties, the cost typically ranges from $150 to $400 per door, including hardware and installation fees. Due to the complexity and scale of the systems involved, commercial installations can be significantly higher, often exceeding $1,000.

Factors That Affect the Cost

Type of System

The cost can significantly vary depending on the type of keyless entry system you choose. Basic systems that use a keypad or fob are generally less expensive than more sophisticated systems that include biometric scanning, Bluetooth [1], or Wi-Fi connectivity. The level of security and convenience features also play a role in determining the price.

Property Size

The size and layout of commercial properties or large residential estates can impact the cost. Larger properties may require more extensive wiring, multiple keyless entry devices, and additional labor, increasing the installation cost.


The quality and brand of the hardware chosen for the keyless entry system can also affect the cost. High-end models with enhanced security features like encryption and tamper alerts tend to be more expensive.

The need for specialized hardware to fit certain door types or integrate with existing security systems can also increase the price.

Number of Entryways

The cost will be directly affected by the number of doors or entryways requiring keyless entry installation. Installing systems on multiple doors often involves more hardware and labor, increasing the overall project cost.

However, some installers may offer discounted rates for installations involving several doors, so it’s worth inquiring about bulk pricing.

Do I Need Professional Help Installing It?

While some keyless entry systems are designed for DIY installation, professional help is often recommended, especially for complex systems or those requiring intricate wiring and connectivity.

Professionals ensure the system is installed correctly and securely, avoiding common pitfalls that could compromise the system’s effectiveness or damage your property.

Advantages of Hiring A Certified Installer

  • Expertise: Certified installers have the necessary knowledge and experience to handle installation challenges and ensure the system operates as intended.
  • Warranty Protection: Manufacturers may require professional installation to maintain the warranty, protecting your investment.
  • Time-Saving: A professional installer can complete the job efficiently, saving time and hassle.
  • Security: Expert installation ensures that your system provides the intended level of security without vulnerabilities.


Can I install a keyless entry on my car?

Yes, you can install a keyless entry system on most cars, enhancing convenience and security. The process may vary depending on the make and model of your vehicle and the type of system you choose.

Is it difficult to install keyless entry?

The difficulty of installing a keyless entry system varies. Simple systems may be manageable for those with basic DIY skills, but more complex systems might require professional installation due to intricate wiring and programming needs.

Is keyless entry the same as key fob?

Keyless entry refers to systems that allow you to lock and unlock your doors without using a traditional key, which can include key fobs, among other devices like keypads or smartphones. A key fob is a specific type of remote used to control the keyless entry system. [2]

How long does it take to install keyless entry?

Installation time for keyless entry systems can range from a few hours for straightforward setups to longer for more complex systems. The exact time will depend on the system’s complexity and the installer’s experience.

Key Takeaways

Keyless entry systems offer enhanced security and convenience for both vehicles and properties. While DIY installation is possible for some systems, professional installation is often advisable to ensure the system is set up correctly and to maintain warranty protection.

Certified installers bring expertise, efficiency, and peace of mind, making them a valuable resource for anyone looking to upgrade their access controls.
