Where to Safely Store Spare Car Keys
Store a spare car key somewhere secure, memorable and separate from the main key: with a trusted person nearby, in a key safe, or shielded well inside the home for keyless fobs. Never hide it on the car or in obvious outdoor spots. Need one cut? Call or WhatsApp 07367 634032.
Getting a spare key cut is the easy part. Deciding where to keep it is where people go wrong — the spare ends up in the same drawer as the main key, or tucked in a magnetic box under the wheel arch, or somewhere so clever that nobody can find it in an emergency. A badly stored spare is a liability dressed as a precaution.
Good storage balances three things: security against thieves, accessibility in a genuine emergency, and protection of the key itself. Here is how to get that balance right. If you do not have a spare yet, our guide on why you need a spare car key makes the case — this post is about what to do with it once you have one.

The golden rule: separate from the main key
Everything else follows from this. A spare kept next to the main key is stolen in the same burglary, lost in the same misplaced bag, and forgotten in the same jacket. The spare earns its keep precisely because it is somewhere the main key is not. Couples should each know where the other's spare lives — emergencies do not check whose key it was. Whatever option you choose below, check it against this rule first.
Good options, ranked by practicality
With a trusted person nearby. A partner, a family member or a trusted neighbour within easy reach is the best storage for most people. In a lockout, one phone call solves it. Choose someone reliably contactable and make sure they know the key is there and what it is for.
In a proper key safe at home. A small wall-mounted or portable key safe with a combination gives you controlled access without relying on another person. Fix it somewhere discreet but memorable — inside a utility cupboard, for example — and do not store the combination next to it.
Well inside the home, shielded if keyless. For a spare you keep yourself, the right place is deep inside the house — an upstairs drawer, a home safe — away from doors and windows. If it is a keyless fob, it needs a Faraday pouch too; an unshielded spare by the front door is a relay attack waiting to happen.
| Storage option | Strengths | Watch out for |
|---|---|---|
| Trusted person nearby | Fastest in a real lockout; no cost | They must be reachable when you need them |
| Key safe at home | Controlled access; always there | Fit it discreetly; keep the code separate |
| Deep inside the home | Simple; under your control | Keyless fobs need signal shielding |
| At work (locked drawer) | Useful for commuters | Only if the workplace is secure |
Hiding spots to avoid
Under the wheel arch or in a magnetic box on the chassis: thieves check these first — it is the oldest trick in the book and it fools nobody. In a plant pot, under the doormat or above the door frame: the classic burglary spots, checked in seconds. In the glovebox or the boot: inside the car the key is meant to open, which helps nobody in a lockout and hands a thief a working key if they get in.
The pattern is simple: anywhere a stranger would look, or anywhere the key travels with the car, is wrong. Cleverness is not security — a spot the thief finds in thirty seconds is not a hiding place.
Special cases worth thinking about
Households with several drivers should decide whose spare is whose and where each lives — labelled, separated, and known to everyone. If you travel, consider whether the spare should move with a housesitter or stay put. For keyless cars, remember the shielding rule applies to every fob, including the one you rarely think about.
And keep the spare's condition in mind: a spare is only useful if it works. Test it once or twice a year — batteries die in drawers too, and a dead spare discovered during a lockout is a miserable moment. For classic cars with simple keys, a spare is so cheap to cut that there is no excuse for only one — get two spares and store them in two places.
Renters, sharers and shared houses
Not everyone has a discreet utility cupboard or a trusted neighbour of ten years. In shared houses and rentals, the calculus shifts: a key safe needs landlord permission to fit, and housemates come and go. The trusted-person option often wins here — a family member or a long-term friend rather than a current housemate whose tenancy ends in June.
Avoid the communal key bowl by the front door, which every shared house seems to have. It is convenient for everyone, including anyone who walks in uninvited. A spare deserves its own private spot, even if that spot is simply a locked drawer in your own room. And if you move out, take the spare's location with you — update the plan the same week, not eventually.
Write down what the spare is and where it lives
Memory is unreliable under stress, and households change. Keep a simple record — not with the key, but somewhere sensible like your phone's notes: which car the spare belongs to, where it is stored, and whose hands it is in. If you move house or the trusted person moves away, update the record and relocate the key the same week.
One caution: do not label the key itself with the car's registration or your address. A lost labelled key is a gift. A small tag with the make, or nothing at all, is enough when the storage location is documented separately. Review the arrangement once a year — people move, relationships change, and the trusted neighbour from years ago may have moved away. A yearly two-minute review keeps the plan real.
When the spare is lost too
It happens: the main key vanishes, and the spare — stored so carefully — cannot be found either, or turns out to have a dead battery. At that point you are in all-keys-lost territory, which is a bigger job: the car needs a new key generated from scratch, usually via the VIN and the vehicle's security system, rather than a simple duplication.
The way back from this is the same lesson, applied twice: get two keys made while you have one, store them in two different good places, and test both yearly. Redundancy only works if the redundant parts actually exist and actually work.
The holiday problem
Holidays break every routine, which is why they deserve their own plan. If the car sits at home for two weeks, the spare should too — with the housesitter or in the safe, not in your suitcase travelling with the main key. If you are driving to the airport, decide in advance: does the spare stay home with someone who can reach the car, or travel with a companion in a separate bag? The wrong answer is both keys in the same luggage, lost or stolen together. And if the car is parked at the airport for the duration, a trusted person holding the spare is worth more than any parking upgrade.
No spare to store? That is the real problem
All of this assumes you have a spare, and many drivers do not — which is why lockouts turn into emergencies. A spare cut while everything works is the cheapest locksmith job there is, done at your home in one visit, and it immediately needs a good home from the list above.

Frequently asked questions
Is it safe to hide a spare key outside the house?
We advise against it. Outdoor hiding spots are the first places thieves check, and a found key gives them the car with no effort.
Should a spare keyless fob be kept in a Faraday pouch?
Yes. Every fob for the car should be shielded when not in use, including spares. One unprotected fob is enough for a relay attack.
Can I keep the spare key in the car?
No. It does not help in a lockout, and if someone gets into the car they drive away with a working key. Keep it separate from the vehicle.
How often should I test my spare key?
Once or twice a year. Check the blade turns the locks and the remote works — batteries fade in drawers just as they do in pockets.
What is the best option if I live alone?
A trusted friend, relative or neighbour nearby is ideal. Failing that, a discreet key safe at home keeps the spare under your control.
