Keyed vs. Keyless Entry: A Locksmith’s Guide to Choosing the Right Lock

Published Date: Sep 29, 2025

Security technology has evolved, giving property owners more choices than ever before. Traditional keyed locks have stood the test of time, but keyless entry locks are gaining more popularity. Which one is right for your property? In this guide, Sure Lock & Key explains the benefits and drawbacks of keyless entry door locks, so you can make the best decision for your home or business.

Understanding Keyless Entry Door Lock Technology vs. Traditional Locks

A traditional lock uses simple mechanics. Insert the right key into the cylinder, and it lines up the small metal pins. Once those pins click into place, the cylinder turns, pulling back the bolt and opening the door.

A keyless entry door lock works differently from a traditional one. Instead of a physical key, it relies on electronic parts and a small motor (called an actuator) to move the bolt. Access can be granted via a keypad, key fob, smart card, or even a smartphone. When the correct code or signal is received, the lock engages or disengages instantly.

The biggest difference? A traditional lock depends solely on its physical structure for security, while a keyless entry door lock adds an extra layer of electronic authentication. This means more flexibility, remote access options, and the ability to create or remove access codes without changing the entire lock.

The Modern Upgrade: What is a Keyless Entry Door Lock?

If you’ve ever wondered “what is a keyless entry door lock?”, the answer is simple: it’s a lock that doesn’t require a physical key to open. These locks range from simple electronic keypads to advanced smart models that connect to Wi-Fi or Bluetooth. The most common type features a numeric keypad where you enter a pre-set code. Keyless entry locks let you give temporary codes to guests or service providers and remove them just as easily. To see how we got from traditional locks to today’s high-tech options, check out the evolution of smart locks.

Keyless Entry Pros and Cons to Consider

Keyless entry systems are more than a modern trend. These systems can make daily life easier, but they also have trade-offs that may not suit every situation. Before you consider the switch, we recommend consulting with a professional home locksmith to weigh the keyless entry pros and cons.

Pros:

Convenience: No more lost, stolen, or forgotten keys. With many keyless entry lock models, you can even lock or unlock your door remotely.
Access Control: Create unique access codes for family, guests, cleaners, or contractors — and delete them instantly when they’re no longer needed. For businesses, a business locksmith can set up similar systems for employee access.
Extra Security Features: Many models include auto-locking features, so you never have to wonder if you remembered to lock the door. Many models can also send you notifications when someone comes or goes.

Cons:

Power Dependency: Most keyless entry locks run on batteries. If the batteries die — and you don’t have a backup key — you could be locked out.
Higher Upfront Cost: Smart locks are generally more expensive than their traditional counterparts.
Potential Vulnerabilities: As with most electronic devices, smart locks aren’t completely immune to hacking. That said, top brands build in strong encryption to keep your security intact.

The Critical Question: Are Keypad Locks Safe?

Due to some drawbacks, there’s a common question: Are keypad locks safe enough to keep your home secure? In most cases, yes — as long as you choose a quality model and have it installed the right way. Well-made keypad locks use strong, tamper-resistant materials and smart design features like backlit numbers for easy use at night. Some even mask button wear, so no one can guess your code. Many will also lock out after several failed attempts, stopping anyone from trying endless combinations.

Of course, the user plays a big role in security, too. Using a strong, unique code and changing it periodically is essential. If you like DIY projects, you can explore our guide on how to install a keyless door lock, but professional installation ensures every feature works exactly as intended.
