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.
Deadbolt Installation Cost by Type
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 Deadbolt Cost
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 Deadbolt Cost
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 Cost
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.
What Factors Influence the Cost to Install a Deadbolt Lock?
Because installing a deadbolt is a pretty simple process, only a few factors come into play when it comes to pricing.
Deadbolt Type
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.
Door Touch-Ups
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.
DIY vs. Hire a Pro
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 |
How Much Does It Cost to Install a Deadbolt Lock Yourself?

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.
