Locked out on Garratt Lane at midnight? Key snapped in the front door of your Victorian terrace on Magdalen Road? Come home to a back door that has been forced open? These are the calls we take every week from people in Earlsfield, and we respond to all of them within 30 minutes.


SMS Locksmith has a mobile unit based locally in SW18, which means we are genuinely nearby when you call. We are not a national call centre dispatching someone from the other side of London. When you ring 020 3369 6009, we can usually tell you how long we will be straight away, because we already know where we are and where you are.


Emergency locksmith situations are stressful. You might be standing outside in the rain, worried about your kids inside, or dealing with the aftermath of a break-in. We get that. Our job is to get you back in, get the property secure, and keep things as calm and straightforward as possible.


What counts as an emergency?

Broadly, anything that means you cannot get into your property, cannot lock it up, or have reason to believe it is not secure right now. The most common emergency calls we attend in Earlsfield include:

       Being locked out of your house, flat or maisonette

       A key that has snapped off inside the lock barrel

       A lock that has jammed and will not open or close no matter what you try

       Coming home to find signs of a break-in or attempted forced entry

       Losing your keys and needing the locks changed before you can sleep

       A tenant, ex-partner or former housemate who still has keys that need cancelling

       A door that has slammed shut with the keys, phone and wallet inside

If you are not sure whether your situation counts as an emergency, call us anyway. We would rather talk you through it on the phone and save you an unnecessary callout than have you stuck outside trying to decide.


How we handle emergency lockouts

We always try non-destructive entries first. If you have simply pulled the door shut behind you, which happens constantly with the Yale-style night latches on older Earlsfield properties, we can usually get you back inside without touching the lock at all. No drilling, no damage, no replacement needed. You get back in, and the lock carries on working as normal.

If the lock itself has failed, that is a different situation. A snapped key, a seized mechanism, or a cylinder that has been attacked all need the lock to be replaced. We carry a full range of replacement cylinders, mortice locks and multipoint mechanisms in the van, so most emergency jobs are completed in a single visit. You are not left waiting for parts or a follow-up appointment the next day.

Once you are back inside, we make sure the door is fully secure before we leave. If we have had to replace the lock, we fit something at least as good as what was there before. If you want something stronger, we can talk through the upgrade options on the spot and fit them there and then.



After a break-in

If your property has been broken into, the priority is making it safe again immediately. We can board up damaged doors or windows, replace compromised locks, and secure the entry point so you are not left sleeping in an unlocked property. We can also carry out a fuller repair or upgrade in the days following, once you have had time to deal with the police and your insurance company.

We attend burglary aftermaths across Earlsfield regularly. Ground-floor flats, rear-access properties and older doors with basic locks are the most common targets. If you have been broken into, we can advise on what went wrong and what to change so it does not happen again.
