Get references from family, friends, or co-workers. Make sure the company is a local locksmith, not a "national" one.
Avoid any firm that answers the phone with a generic phrase such as "locksmith services" rather than with a specific company name.
Be wary of those who claim to be a "locksmith" and arrive in unmarked cars or vans. Texas, by law, requires all locksmiths to have their company name and company license number on all service vehicles.
Ask for a picture ID. Texas is 1 of only 14 states that require, by law, that all locksmiths carry proof that they are licensed. It will look similar to a drivers license, but will say PRIVATE SECURITY REGISTRATION (top/front), Issued By TX DPS (bottom/front) and Reg. Type: Locksmith (top/back) of the license.
Get an accurate written estimate on company letterhead, with any parts costs, labor/installation costs, service call price, or any other fees, before work begins. Get a receipt after you pay.
If you’re locked out or looking for a simple re-keying job, be wary of those who recommend or insist on drilling and replacing the lock. Drilling is typically only needed to open high-security locks. We have never run into a home owner who had high security locks on their house and didn't know it!
Go with you gut! It's not lying to you.
If you get an uncomfortable or uneasy feeling about the individual that shows up, don't be afraid to refuse their services. Scammers have no problem charging $1,000 for a job that should only cost $150-$200, so protect yourself and your wallet.
