How Much Does It Cost to Replace a Door Lock Cylinder?

Getting locked out of your home or apartment can be extremely inconvenient and stressful. Often, the quickest and easiest solution is to replace the door lock cylinder rather than call a locksmith to pick the lock or make duplicate keys. But how much does it actually cost to replace a door lock cylinder on your own?

Factors That Influence Cost

Several variables affect the total price of replacing a door lock cylinder:

  • Type of lock: Entry door locks tend to cost more than interior door locks. Deadbolts are generally more expensive than doorknob locks. Keyless and smart locks have the highest prices.
  • Brand: Well-known lock brands like Schlage and Kwikset are pricier than generic no-name locks. You pay for the brand name reputation.
  • Quality: Higher security locks made with sturdy materials, like solid brass cylinders, cost more than average basic locks.
  • Features: Locks with added features like antique-style levers or satin nickel finishes add cost. Keyless touchscreen locks are at the high end.
  • Retailer: Big box stores may charge less than local locksmith shops or online-only retailers. But a locksmith may include installation in the price.

Cost Range

Here are some typical costs for replacing common residential door lock cylinders:

  • Basic interior door lockset: $10 – $30
  • Solid brass entry door deadbolt: $40 – $70
  • Keyless touchscreen deadbolt: $150 – $250
  • Smart lock with WiFi connectivity: $200 – $350

The price ranges account for different brands and features. High-end electronic keyless and smart locks sell for significantly more than traditional keyed locks.

Additional Costs

Besides the lock cylinder replacement, also factor in potential costs for:

  • Locksmith service fee for installing the new cylinder ($50-$100/hr)
  • New matching keys ($3-$10 per key)
  • Additional tools needed like a drill, screwdriver, tape, etc.
  • Repairing any door damage from breaking in previously

Saving on Replacement Cost

Here are some tips to get the best deal:

  • Shop sales at home improvement stores for discounts on lock brands. Sign up for loyalty programs and e-newsletters to get coupons.
  • Buy generic equivalents rather than name brands if you are on a tight budget.
  • Consider used or refurbished smart locks which are much cheaper than new.
  • Buy a standard lock and install it yourself rather than hiring a locksmith. Watch DIY videos to learn.
  • Buy a rekey kit which allows you to rekey the lock to your existing key rather than replace everything.

Replacing a lock cylinder is an affordable DIY home improvement project. With some smart shopping, you can likely find a quality replacement lock cylinder for $50 or less. Paying a locksmith for installation and changing all your keys raises the total cost significantly. But the peace of mind in securing your home with an upgraded lock makes it a wise investment.
