The most popular types of keyless entry door locks are keypad locks and smart locks. While keypad locks are less expensive, smart locks offer more customization and features to meet your needs. Some locks may be a combination of the two types.

Most keyless entry door locks are deadbolts that require a separate knob or handle to open. Deadbolts lock from outside or with a thumbturn inside and are usually more secure than lever handle or knob locks.

Also available are mechanical keyless entry locks, which are often less expensive than electronic locks and don’t have the issue of locking you out should your home lose power.

A mechanical keypad lock uses a keypad and mechanical deadbolt to unlock. No batteries means no loss of functionality if the lock loses power, and any issues will be mechanical rather than electronic. For a hassle-free option, mechanical locks get the job done.

Pros:

• No losing power

• Easy to program

• Reliable

• Less likely to be damaged by weather

• Least expensive option

Cons:

• Limited to one code

• Lack of back-lit keypad

• No remote unlocking or other features of electronic locks

Price: Mechanical keypad locks range in price from $40 to $140.

Using a keypad lock is as simple as setting a code and committing it to memory. It eliminates the need for a key, fob, or smartphone app (though some keypad locks can use any of these as well). Many keypad locks offer additional codes, which can be useful if you need to grant temporary access to a repairperson.

Here are some things to think about if you’re looking at keypad locks that do not include fobs or smart features.

Pros:

• Easy to use

• No app or home system needed

• Easy to add more codes

• Less expensive option
   

Cons:

• Lacks features

• No remote unlocking

• May be susceptible to weather damage

• May be susceptible to hacking

• Need to replace batteries

• No access if power goes out/batteries die
   

Price: Keypad locks range in price from $80 to $200.

What makes a lock “smart” is the ability to connect to an app or sync with a home security system. Smart locks are ideal for anyone who needs maximum control and customization. Features can include remote unlocking via app, tracking who enters, voice control, and electronic key sharing.

Smart locks are a good choice for busy families who have frequent guests needing access. If you’re already used to keeping tabs on your home with a smart home security system, smart locks are a great fit.

Pros:

• Flexibility

• Plenty of features

• Multiple unlocking methods

• Syncs with home systems
   

Cons:

• Requires WiFi connection or hub

• Takes longer to set up

• May be susceptible to hacking

• Need to replace batteries

• May be susceptible to weather damage

• No access if power goes out/batteries die

• More expensive option

Price: Smart locks range in price from $120 to $250.

A subset of smart locks, biometric locks enable users to unlock the door using fingerprints. Entry is as simple as pressing your finger on a sensor pad.

Here are some factors to bear in mind if you decide to choose biometric locks.

Pros:

• Easy to use

• Easier for children to use

• No risk of stolen codes

• Stores hundreds of fingerprints
   

Cons:

• May be damaged by weather

• May be susceptible to hacking

• Need to replace batteries

• No access if power goes out/batteries die

• Most expensive option
   

Price: Biometric fingerprint locks range in price from $130 to $250.

Not every keyless entry door lock comes with all the latest bells and whistles, and some have so many features that you may not understand what each one does. To help you find the best keyless entry lock for your situation, take a look at these popular features.

While a keyless entry door lock can’t replace a home security system, it can supplement one. Smart locks are most likely to have an alarm, which can alert you via an app in the case of forced entry. For the most control and security, choose a lock with a built-in alarm.

Many keyless entry door locks have batteries, and those batteries will need to be replaced anywhere from every three months to every year and a half. If the battery dies, you could be locked out if you don’t have a lock that also takes a key. You can avoid the problem with a solar-powered lock. These locks are convenient but can be more expensive, and the door must be exposed to some sunlight.

While it may seem like an odd feature for a keyless entry door lock, a keyhole can be convenient in certain circumstances. If your keyless lock is difficult to program or doesn’t have the capability to add electronic codes, you can easily lend a key to a guest. The drawbacks are that you could lose your key, and a keyhole can potentially be picked.

Opting for a keyless lock that uses a key fob means you don’t need to remember codes or use smartphone apps, making it a good choice for families with children. Most key fobs generate random codes each time the door is unlocked, so that there’s no risk of a stranger using another fob to unlock the door. The drawbacks are that the fob’s battery will eventually die and may be difficult to replace, and, of course, fobs can be lost.

Just like the locks on hotel room doors, a keyless lock that enables you to swipe a card with a magnetized strip through a reader is faster to use than a keypad. However, the magnetic strip may eventually wear out, locking you out.

A keyless lock with a proximity sensor enables you to unlock the door automatically just by having your key card, fob, or smartphone nearby. This is as convenient as it gets – unless you forget your card, fob, or phone, in which case you’d better hope you remember your keypad code (if you even have a keypad).

Your lock is worthless if it can’t keep indtruders out. Deadbolt keyless entry locks tend to be the most secure. Knob and lever handle locks (where the lock is built into the knob or handle) can potentially be forced open. Review the durability rating of your lock of choice before buying. You should also consider the possibility of weather damage, particularly with some smart locks.

• Set up the keypad code or electronic code before installing your lock. That way, you won’t lock yourself out.

• Conceal the keypad as you enter the code. Treat your keyless lock code just as you would a bank PIN. If someone were to observe the code being entered, they would have access to your home. Also, consider changing your code frequently.

• Check the integrity of your door before installing a keyless entry door lock. Make sure your hinges are secure and undamaged (and unexposed to the outside). If there’s a window near the handle or knob, you might want to consider purchasing a new door to prevent burglars from simply breaking the glass and turning the handle.

Q. Can I install a keyless entry door lock myself?
A. Yes, and most old locks can be easily replaced with keyless entry locks. You may feel more secure having a locksmith do the job, but you shouldn’t need too many tools or much time to install the lock yourself.

Q. What happens if the lock battery dies?
A. Most locks feature a low-battery warning. If the battery does die, there’s a chance you’ll be locked out. If your lock features a traditional keyhole, you can still unlock it that way, and some keypad locks can still be unlocked without power. As a last resort, you might be able to use your lock’s override feature.

Q. Are keyless entry door locks safe?
A. That depends on factors like strike plates and door material, in addition to the quality and type of lock itself. The durability of locks varies, but a well-constructed keyless entry deadbolt lock should be as secure, if not more, than a standard deadbolt. Many smart locks include added safety features like an alarm system and notification when visitors arrive.
