Almost nobody thinks about a spare car key until they are standing next to a car they cannot start. It is one of those small, dull, easy-to-postpone jobs that turns out to matter enormously — because the difference in cost and stress between “copying a key” and “replacing the only key” is large. Here is the case for getting a spare cut now, while you still have one to copy from.
When you have a working key, making a spare is the easy version of the job: the locksmith copies the blade and clones or programs the chip alongside the key you already hold, with no need to touch the car’s security system. When you have lost your only key, the same car becomes an “all keys lost” job — the immobiliser has to be accessed and reset from scratch, which takes longer and costs more. Cutting a spare today is, quite simply, the cheap version of a bill you may otherwise pay later.
A spare saves the thing money cannot: time, on the worst possible day. Lose your only key on a school run, before a shift, or far from home, and you are stranded until a replacement is cut and programmed. A spare in a drawer turns a stranded afternoon into a minor inconvenience.
A spare is sensible for everyone, but some situations make it close to essential:
Bring the car, the working key, and your proof of ownership to a mobile auto locksmith — or have them come to you. With a key to copy from, most spares are cut and programmed quickly and at the roadside. As ever, a reputable locksmith will check ownership before cutting anything, and quote an all-in price for your specific make and model up front.
A named, vetted master locksmith covers your area — no call-out fee.
A spare only helps if you can reach it when the first key is gone — so keep it somewhere safe but separate from the original, not on the same ring or in the same bag. A trusted family member, a home key safe, or a dependable drawer all work. The one place it should never live is inside the car.
It is a small job with a large payoff. If your car has only one key, booking a spare is the single most cost-effective thing you can do for your motoring peace of mind — and far cheaper than the call you would otherwise make from a car park one day.
Most car lockouts are an inconvenience, not a danger — and a mobile auto locksmith opens the car without a scratch. What to expect, and when to call 999 instead.

Before you force it — why windows jam, the safe way to free a stuck handle, sash or seized mechanism, and why it is usually the lock that has failed, not the whole window.
