Cost to rekey locks in Maryland|How Much Does It Cost to Rekey Locks in Maryland?

If you’ve recently moved into a new home, lost a set of keys, or want to tighten up security without replacing every lock in the house, rekeying is probably on your radar. But what does it actually cost to rekey locks in Maryland — and is it worth it? Let’s break it all down so you can make an informed decision.

Cost to rekey locks Maryland|Does ‘Rekeying a Lock’ Actually Mean?

Rekeying is the process of changing the internal pins inside your existing lock so that the old key no longer works. A locksmith replaces the tiny pin stacks inside the lock cylinder, and cuts you a brand new key. The lock hardware itself stays exactly the same — only the internal configuration changes.

It’s faster than a full lock replacement, costs less, and achieves the same security goal: making sure old keys no longer work on your locks. It’s one of the most cost-effective security upgrades you can make.

Average Cost to Rekey Locks in Maryland

Here’s what you can realistically expect to pay when hiring a locksmith to rekey your locks in the Baltimore and Catonsville area:

Per-Lock Pricing

Rekeying a single lock typically runs between $20 and $40 per lock, plus a service call fee that usually ranges from $25 to $75 depending on the company and time of day. Most locksmiths will charge a flat visit fee and then a per-lock rate after that.

Rekeying a Whole House

For a standard home with 3–5 exterior locks, the total cost to rekey in Maryland typically falls between $75 and $200 all-in. If you have additional locks — deadbolts, garage entry, patio door — the cost increases slightly per lock but the visit fee doesn’t change.

After-Hours and Emergency Rekey Costs

Need rekeying done late at night or on a weekend? Expect to pay a premium of 30–50% above standard daytime rates. For most Maryland homeowners, this means emergency rekeying costs between $120 and $280 for a standard house. Still far cheaper than a break-in.

Rekeying vs. Replacing Locks — Which Is Better for You?

This is the most common question we hear. The honest answer is: it depends on your situation.

When Rekeying Makes More Sense

Rekeying is the smarter choice when your locks are in good condition but you just need to change who has access. This is ideal after moving into a new home, after a roommate or tenant moves out, if you’ve lost a key, or if you want all your locks to work on a single key (master rekeying).

When You Should Replace Instead

If your locks are old, worn, damaged, or are low-security models you want to upgrade, replacement makes more sense. Replacing locks also gives you the opportunity to upgrade to higher-security or smart lock options. Lock Maven can help you assess which route makes more sense for your home.

What Affects the Cost to Rekey Locks in Maryland?

Number of Locks

The more locks you need rekeyed, the better value you get per lock. A single lock might cost $60 all-in; five locks might cost $150 total — a much better per-lock rate.

Type of Lock

Standard deadbolts and knob locks are the easiest and cheapest to rekey. High-security locks (Medeco, Mul-T-Lock) have more complex pin systems and may cost slightly more. Smart locks generally cannot be rekeyed in the traditional sense — they require reprogramming instead.

Time of Day and Emergency vs. Scheduled

Scheduling a rekey during business hours will always be cheaper than an emergency call at midnight. If your situation isn’t urgent, booking a daytime appointment with Lock Maven can save you $30–$80.
