Why Get a Duplicate
Don't Wait Until You're Locked Out
Having a spare key is one of the cheapest forms of insurance against a stressful lockout. Making a duplicate now — while you have your original — is far less expensive than emergency lockout or key replacement service later. CT Locksmith Service LLC makes duplication fast and affordable.
- Spare key for a family member or trusted person
- Backup in case your primary key is lost or damaged
- Spare for a rental property or Airbnb
- Duplicate for a new employee or housecleaner

FAQ
Frequently Asked Questions
How long does key duplication take?
Standard house and office keys are typically duplicated in 2–5 minutes at our store. Car keys requiring programming take 30–60 minutes.
Can you duplicate a 'Do Not Duplicate' key?
We require proof of authorization for restricted keys. Please bring identification and proof of your right to duplicate the key.
Do you duplicate car keys with transponder chips?
Yes. We cut and program transponder chip keys on-site — a standard hardware store cannot program the chip, which is required to start modern vehicles.
Can I get a key duplicated without the original?
For car keys, yes — using your VIN and proof of ownership. For house keys, you typically need the original or the lock present.

Beware of Nationwide Call Centers
Many "locksmith" ads route you to out-of-state call centers that quote a low price, then send an unlicensed subcontractor who charges 3–5× more on arrival. Always get the full, total price upfront before anyone comes out — and confirm they're local and licensed.
We're a locally owned CT-licensed shop (CT #LCK.0000220) with a real address in Bethany. You talk to the owner, you get the real price, and a licensed tech shows up.
