Verifying a Merrimack locksmith before you hire
NH does not require a state locksmith license, which makes verifying a locksmith's credentials especially important in Merrimack. Before hiring any locksmith, including One Source Security, we recommend:
- Verify the address (674 Daniel Webster Hwy, Merrimack, NH 03054) on Google Maps Street View — a real shop or office, not a residential address or empty lot
- Ask on the phone for a complete price quote with service call, labor, and parts as separate line items
- Confirm credit card payment is accepted (cash-only demands are a red flag)
- Check that the phone number (+1 603-645-5969) appears consistently on their website, vehicle, and any invoices
- Read recent Google reviews — One Source Security is one signal, but read individual reviews to spot patterns
