The 5 Types of Locksmith Services (And When You Need Each)

Which Locksmith Service Do You Need?

Start with the problem: who has access, what hardware failed, whether you are locked out, whether the issue is a vehicle key, and whether the door is residential or commercial. Then route to the service that owns that intent.

• Old keys still work: rekey locks
• Worn or upgraded hardware: lock change
• Locked out of a home: residential lockout service
• Lost or broken vehicle key: car key replacement
• Business credential control: access control systems or master key systems

Rekeying Changes Access Without Replacing Hardware

Rekeying is for serviceable locks when the hardware still works but old keys should no longer operate that cylinder. It is common after moving, tenant turnover, a lost key, or a change in who should have access. Compare the parent decision in the rekey vs replace guide.

• Best fit: working lock, access list changed
• Not enough: worn hardware, broken parts, wrong function, or smart-lock upgrade
• Published GLC range: $19-$110+ per lock

Lock Replacement and Installation Change the Hardware

Lock replacement or installation is the right category when the lock is worn, damaged, mismatched, missing the function you need, or being upgraded to new hardware. Residential lock changes, smart locks, commercial locks, and keypad hardware each have different fit and code considerations.

• Residential hardware: lock change or smart locks
• Commercial hardware: commercial lock replacement or keypad locks
• Published residential lock-change range: $65-$315+ per lock including hardware and labor

Lockout Help Is About Safe, Authorized Access

A lockout is different from a rekey or replacement because the immediate problem is access. The locksmith should verify authorization, explain the quote, and avoid giving bypass instructions. For safety-first guidance, use the Dallas car lockout guide or Garland house lockout guide.

• Call 911 first for life-safety emergencies
• Have proof of ownership, residence, or authorized use ready
• Published GLC lockout range: $45-$190+

Automotive Locksmith Services Are Vehicle-Specific

Automotive locksmith work can include car lockouts, basic cut keys, transponder keys, key fob programming, smart keys, and ignition service. The exact year, make, model, key type, and ownership proof decide whether mobile service is available and what range applies. Start with the car key types guide if you are unsure what you have.

• Basic cut key: $85-$190+
• Transponder key: $95-$440+
• Smart key or push-button start: $250-$565+
• Key fob programming: $65-$375+

Commercial and Security Planning

Commercial locksmith work may involve door hardware, access control, master keys, keypad locks, exit devices, closers, and high-security locks. Security upgrades for a home or business should start with the opening and the access problem, not a generic product claim. For residential prevention, see the home security guide.

• Managed credentials: access control
• Mechanical hierarchy: commercial master key systems
• Commercial lock hardware: commercial lock replacement
• Higher-security commercial hardware: high-security locks
