FAQ

Common questions

How quickly can you reach me in an emergency?+

For most jobs across South Yorkshire we aim to be on site within 30–60 minutes. Call 07908 180451 and we'll give you an honest ETA.

Do you charge a call-out fee?+

For an accurate quote please call or WhatsApp us. We'll confirm the price before any work starts — no surprises.

Are you insured?+

Yes — ASG Locksmith Limited holds full public liability insurance and our locksmith is DBS checked.

Can you open my door without damaging it?+

In most cases yes. We use non-destructive entry techniques wherever possible to save you the cost of a new lock.

Do you cover commercial premises?+

Absolutely. We work with offices, shops, landlords and businesses — from emergency lockouts to scheduled security upgrades.

Do you offer safe opening services?+

Yes — we open home and business safes, including lost combinations, jammed mechanisms and emergency access. We always aim for the safest, least invasive solution, but depending on the type of safe and the condition of the lock or mechanism, destructive entry may be required. In many cases this means the safe may not be reusable afterwards. Call or WhatsApp us first to discuss your safe.
