5 Very Important Things to Consider When Hiring a Locksmith


1. There's no such thing as a $19 Locksmith. The old bait and switch. STAY AWAY! 

2. Get a accurate quote over the phone. Especially for basic work like lock re-key or lockout service

3. Look for a marked car with company name & logo

4. Always ask for a business card or receipt with company name, address & phone number

5. Lastly, not hiring a professional Locksmith can result in high scam prices or repair costs.


Ask about our coupons. Take $10.00 off your total bill when you follow this link and leave a review.
