First, Work Out What's Actually Happened
Lost Somewhere at Home
The most common scenario, and the one most likely to resolve itself with a proper search rather than a phone call. If you're confident the keys never left the house, this is worth fifteen minutes of your time before considering anything else.
Lost While Out and About
Harder to retrace, but not hopeless. Think about the last three or four places you definitely had them: the car itself, the shop counter, the changing room, a friend's sofa. A quick call to any of those locations often solves it faster than you'd expect, particularly if you paid by card and have a rough timeline from your bank app.
Stolen, or You're Not Sure
If your keys were taken, whether from a bag, a coat on a hook, or a break-in, this isn't a search problem any more, it's a security problem. Skip straight to protecting the car below and call the police for a crime reference number before anything else.
Whichever category you're in, our lost or stolen car keys service covers the replacement and security side once you've reached the point of needing new keys. This guide is about the decisions to make before you get there.
The Systematic Search: Do This Before You Call Anyone
Most "lost" keys are actually just misplaced, and a proper search finds them more often than people expect. Skip the frantic re-checking of the same coat pocket three times and work through it properly instead:
Every Pocket, Once Each
Coats, trousers, bags, and anything you were wearing or carrying today. Do it once, properly, rather than repeatedly patting the same jacket.
Retrace Your Last Hour
Where did you last definitely have the keys in your hand? Work forward from there rather than searching randomly.
Check Any Key Trackers
If you've got an Apple AirTag, Tile, or similar attached to your keyring, check the app now. It's often the fastest way to rule a location in or out.
Check the Car Itself
Boot, glovebox, under the seats, and door pockets. It's more common than people admit for keys to be in the car the whole time.
If they're genuinely nowhere and the car itself is locked with the keys inside rather than truly lost, that's a different problem with a much simpler fix. Our locked out of your car guide covers exactly that scenario.
Keep Searching, or Call Now?
There's a point where continuing to search costs you more than it saves, especially if you need the car soon. A few honest questions help decide:
Do You Have a Spare?
If a family member or housemate can bring a spare within the hour, that's almost always quicker and cheaper than a replacement key. Worth a text before anything else.
Have You Searched the Likely Places Twice?
Once properly, then a second pass after a cup of tea. People often walk straight past keys the first time simply because they're stressed.
Do You Need the Car in the Next Few Hours?
If yes, it's usually worth calling a locksmith now and continuing to search while they're on the way, rather than searching first and calling later.
If you land on "call someone," that's what we're here for. Speedy Keys covers all of Essex, 24 hours a day, 365 days a year, on 07791 205 595.
Protecting the Car While You Decide
Whether your keys are genuinely lost or possibly stolen, a few precautions cost nothing and reduce the risk while you work out next steps.
Move the car somewhere well-lit and, if you can, somewhere with a degree of natural oversight rather than a hidden corner of a car park. Don't leave a spare key hidden on or near the vehicle, even briefly, since that's exactly the kind of hiding place most people try first. If you're at all unsure whether the keys were lost or taken, treat it as stolen for the purposes of protecting the car, and downgrade your response later if it turns out to be a simple misplacement.
If there's any chance the keys were stolen
Report it to the police and get a crime reference number before calling us. We can then recode your vehicle's immobiliser so the missing key stops working entirely, and supply new programmed keys in the same visit. Call 07791 205 595 once you've reported it.
Keyless Entry: The Extra Risk Most People Miss
If your car has proximity keyless entry, a lost or stolen key fob is a slightly different problem to a traditional key. Keyless fobs constantly broadcast a short-range signal, and criminals with relay equipment can, in some circumstances, capture and amplify that signal from surprisingly far away, including through a wall, to unlock and start a car without ever touching the fob.
This matters most if the fob is genuinely missing rather than sitting on a shelf near your front door. If a keyless fob is lost or stolen, don't wait to see if it turns up. Recoding the vehicle's system so that fob no longer works is the only way to close the risk completely, and it's something we can do in the same visit as supplying a new key.
What Happens Once You Call
Once you've decided it's time to call rather than keep searching, the process itself is straightforward. Tell us your location, vehicle details, and whether the keys are lost or stolen, and we'll dispatch a mobile technician to you, usually within the hour anywhere in Essex. From there, we can gain entry if the keys are locked inside, cut and programme a full replacement, and recode your immobiliser if security is a concern, all in a single visit.
For the full detail on pricing, what to have ready, and exactly how replacement keys are cut and programmed, our lost or stolen car keys page covers that in full. If you're curious about the technical side of how a key gets paired with your car's immobiliser, our how car key replacement works guide goes into that in more depth.
Worth considering while a technician is already at your car: getting a spare key cut on the same visit. Our spare car keys service means the next lost key is a two-minute fix rather than another callout.

Frequently Asked Questions
Work backwards from the last place you're certain you had them, rather than searching randomly. Check every pocket once properly, look inside the car itself including the boot and glovebox, and check any key tracker app if you use one. A second, calmer pass after a short break often succeeds where the first frantic search didn't.
Yes, if they know which car the keys belong to. This is exactly why we recommend not leaving anything with your registration or address on the same keyring, and why recoding the immobiliser is worth doing if there's genuine uncertainty about where the keys ended up, not just when they were clearly stolen.
A straightforward misplacement doesn't need a police report. If there's any indication of theft, such as a broken window, a bag going missing, or a break-in, report it and get a crime reference number, both for your own security and because your insurer may require it for a claim.
Potentially, yes. Keyless fobs broadcast a signal that in some circumstances can be captured and relayed by someone nearby. If a keyless fob is genuinely lost or stolen rather than just misplaced at home, it's worth recoding the vehicle's system so that fob stops working, which we can do at the same time as supplying a new key.
Not usually, and it can be useful to keep as a spare provided you're confident it was genuinely misplaced rather than handled by anyone else in the meantime. If there's any doubt about where it's been, it's worth having it deauthorised rather than kept active on the system.
Many drivers find it genuinely useful. A small tracker attached to a keyring can turn a lengthy search into a two-minute job by showing the keys' last known location. It's a cheap precaution, though it's still worth having a spare key cut as a backup, since a tracker only helps if the keys are simply misplaced rather than lost somewhere inaccessible.
That's a much simpler situation than a genuine loss. We can gain entry without any damage using non-destructive tools, usually within minutes of arriving. See our full guide on being locked out of your car for the complete process.
A focused fifteen to twenty minute search covering your pockets, the last places you had the keys, and the car itself is usually enough to know whether they're genuinely lost. If you need the car soon, it's often more efficient to call while you continue searching rather than waiting until you've exhausted every option first.
