Frequently asked questions
How should I choose a locksmith in Boston?
Start by checking recent online reviews and verifying the business name and phone number. Ask for an upfront estimate, confirm that the technician will show identification, and make sure the company can describe the work they will perform before they begin.
What factors affect the cost of locksmith services?
Price varies with the type of job (lockout, rekey, new lock installation), parts required, and whether service is needed after hours or on holidays. Always request a clear estimate that separates labor and parts so you can compare vendors.
What should I check before the locksmith works on my lock?
Confirm the technician’s identification and the company name, get a written estimate, and ask what methods they plan to use so you understand whether the lock will be repaired, rekeyed, or replaced. If possible, read recent customer reviews for consistency on similar jobs.
