Sure, replacing a deadbolt lock is most definitely a wise investment for your business or home security. However, for people with not much knowledge on them and with so many options on the market, it can certainly leave you wondering how to choose the right one for your needs if you are not relying on a locksmith’s opinion. That’s where your friends at Expert Locksmith Aurora come in! We’ve compiled a basic guide to help you choose the best deadbolt lock for your home. Let’s dive in!

#1: Determine the Type of Deadbolt Lock Needed

Before purchasing and replacing a deadbolt lock, it’s important to determine the type that is best suited for your needs. Is it a single-cylinder? Maybe double-cylinder? Or would a smart lock be the go-to choice? These are the three main types of deadbolt locks you will generally have as options to choose from.

  • Single-Cylinder Locks: These are the most common type of deadbolt lock. They have a key cylinder on the outside and a thumb turn on the inside. They’re easy to use and install, but they can be vulnerable to break-ins if the cylinder is picked or bumped.
  • Double-Cylinder Locks: These locks require a key to lock and unlock both from the inside and outside of the door. They’re more secure than your single-cylinder locks, but can still pose a risk in emergency situations where a quick escape is necessary.
  • Smart Locks: These are the newest type of deadbolt locks that technology and engineering have made available, and can be controlled with a smartphone, keypad, or fingerprint scanner. They can be considered the most secure type of lock, but can also be more expensive and likely to require a power source.

#2: Measure the Size of the Lock

Before purchasing and replacing a deadbolt lock, you need to also measure the size of the existing lock. This will help ensure that the new lock will fit correctly in the existing hole in the door. The standard size for a deadbolt lock should be 2 ⅜ inches or 2 ¾ inches.

#3: Look for High-Quality Materials

The quality of the materials used in the deadbolt lock can impact its durability and effectiveness. Look for locks made from high-quality materials like solid brass or steel. These materials are more resistant to corrosion and wear, making them a more reliable option for your home security.

#4: Check the Lock’s Security Rating

Deadbolt locks can have different security ratings based on their ability to resist break-ins. Look for locks that have a higher security rating, such as those rated by organizations like ANSI or UL. These locks have been tested for their ability to withstand forced entry and are a reliable choice for your home security.

#5: Consider Rekeying the Locks

If you don’t want to go through replacing a deadbolt lock and want to keep your existing one instead, but don’t want to use the same key, you may consider rekeying the lock. This is a process where the existing lock is adjusted to work with a new key. It’s may be the more cost-effective option than replacing the entire lock in certain situations, and can provide the same level of security. Always make sure to work around your needs and weigh in short and long-term benefits.

#6: Hire a Professional Locksmith

If you’re not confident in your ability of replacing a deadbolt lock yourself, it’s best to hire a professional locksmith. They can ensure that the new lock is installed correctly and is functioning properly. A locksmith can also provide advice on the best type of lock for your specific needs.

#7: Check Local Building Codes

Some areas have specific building codes that dictate the type of deadbolt lock that must be used. Check your local building codes to ensure that the new lock you choose is compliant with the code. Failure to comply with these codes can result in fines or even legal action.
