The average cost to install a deadbolt lock is $150, but it can cost between $40 and $200, depending primarily on the type of lock.
Hiring a pro for a deadbolt lock generally only includes labor costs—the full installation cost will vary based on what type of lock you choose. You can also save money by choosing to roll up your sleeves and install a deadbolt lock yourself.
Deadbolt installation typically costs between $40 and $200, including the lock and installation equipment, but the price varies by several factors. For instance, if you decide to install a deadbolt lock yourself rather than hire a pro to do it, then your price will likely be lower. The cost to hire a locksmith includes a minimum fee of $50 to $100 to come to your home, which you'll need to pay in addition to the cost of the deadbolt lock.
If you're purchasing a new lock, the type of deadbolt you choose affects the overall cost to install it as well as its individual pros and cons. Different deadbolt types will be best for different families.
| Lock Type | Average Cost |
|---|---|
| Single | $20–$70 |
| Double | $40–$80 |
| Keyless | $50–$200 |
Single-cylindrical deadbolts are the most common type of residential deadbolt lock. This type is probably what you picture when you hear the term “deadbolt.” These locks feature a cylinder on one side, which requires a key to unlock it. The other side features a thumb turn, which you can use to unlock the deadbolt by turning it with your hand. Single-cylindrical deadbolts typically cost $20 to $70.
Double-cylindrical deadbolts, aka double-keyed locks, are similar to single-cylindrical deadbolts, except they feature a cylinder on both sides rather than one side. As you may have guessed, you’ll need a key to unlock it from the inside as well as the outside.
Since double-keyed locks always require a key to open them, they can be dangerous in the event of a fire or another emergency that requires you to leave your home quickly, so they're typically best for residential properties with specific security needs. Double-cylindrical deadbolts usually cost around $40 to $80.
Keyless deadbolt locks are unlocked by entering an access code on a keypad or touchscreen rather than using a physical key. Because they eliminate the need for a key, they're incredibly convenient, but they also cost more than other deadbolt types. Keyless deadbolts typically cost $50 to $200.
Because installing a deadbolt is a fairly simple process, only a few factors affect pricing.
Most homes use a single-cylindrical or keyless deadbolt, which both vary in price. You can typically purchase a single cylindrical deadbolt for $20 to $70, while keyless deadbolts can cost anywhere from $50 to $200 or more, depending on the type you purchase.
You may need to do a bit of work to cover up any holes from a previous lock or touch up the paint from any damage during installation. Costs to touch up your door after installing a deadbolt lock can range from a few dollars for wood putty or spackle to nearly $100, depending on the work needed and the tools you have on hand.
If you choose to hire a local locksmith to install your deadbolt, then you'll need to pay their service fee in addition to the cost of the lock. Most locksmiths charge a minimum of $50 to $100 to come to your home. If your door is metal, a locksmith may charge an additional fee, usually $25 to $50 extra, since these doors are harder to drill into than other types of doors. You'll want to factor these added costs in when budgeting for your deadbolt installation costs.
| Installation Type | Average Cost |
|---|---|
| Locksmith | $50–$100 minimum |
| Metal door add-on | $25–$35 |
| DIY | Cost of hardware and tools only |
Since locksmiths usually charge a minimum fee of $50 to $100 to come to your home, you can save that amount by installing a deadbolt lock yourself. Installing a standard deadbolt is a fairly straightforward process that many people can learn by watching and reading tutorials online.
If you install the lock yourself, you only need to pay for the lock and the tools required to install it, which typically include a power drill, a hole saw, and drill bits. Power drills usually cost around $30 to $100 and often come with the drill bits you'd need for a deadbolt installation. Hole saws, which cut the hole required to install your lock, can be attached to your power drill similarly to a bit. They usually cost around $10 to $50.
Yes, but adding a deadbolt to some door materials, like steel, may make installation a little bit trickier. For these materials, you will want to hire a locksmith to do the work for you, but be aware that they may charge an additional fee of $25 to $50 or more.
Standard residential deadbolt locks come with a steel bolt that locks your door into place using a key (or keypad) on one side and a thumb turn on the other. When you lock it, the bolt slides into a strike plate on your door jamb to secure your door shut.
The benefit of deadbolt locks is that they're much harder to force open than simple locks with pin tumbler mechanisms, so they may offer added security. This feature is why many locksmiths recommend deadbolts for home security. For many households, this added protection and peace of mind is well worth the cost of installing a deadbolt.
Smart deadbolts are a good option for homeowners who want more convenience and extra features. They offer keyless entry and remote access and can integrate with existing smart home systems, making them very versatile. Smart deadbolts also often come with advanced security features like tamper alerts. The downside is that they are more expensive than traditional deadbolts and do need batteries.
