Spare Car Key Duplication
The proximity fob has ridden in a pocket for years, the range feels shorter than it used to, and a dashboard warning mentioned a battery a while back.
In plain words
A vehicle used by more than one person, such as a shared family car, a small business van or a vehicle looked after by a caretaker, works better with a key for each regular driver rather than one ring changing hands. Spare key duplication from the working original gives every driver an independent, fully tested key: matched blade, matched chip or remote code, and confirmed operation in every door and the ignition before anyone leaves. Keeping a record of how many keys exist and who holds each one also makes accounting for all of them simpler later on.
How the visit goesThe blade on the everyday key has gone shiny and thin along one edge, and lately it needs a wiggle before the ignition catches. Nobody wants to be holding a failing original with nothing waiting in reserve if it finally gives out.

How the visit goes


Looking at the working key itself
The existing key is examined for exactly what it is: a plain blade, a blade carrying a transponder chip, a remote head with buttons built into the plastic, or a proximity fob meant to stay in a pocket. Wear matters too; a blade that has thinned unevenly or a button that sticks tells the locksmith what to expect when it is time to trace or copy from it, and whether the original itself might be due for retirement once the spare exists. A key that has already been altered, filed or repaired is noted before it becomes the reference for a new copy.
Working from a used or single-key vehicle
When only one key exists for the vehicle, the whole process leans on that single copy: its blade is traced or measured, its chip is read where the system permits it, and every remote function it performs is noted before work starts, since there is nothing else to check against. The new key is built to match, then tested on its own, away from the original, to confirm it genuinely operates independently rather than only appearing to work while the first key happens to be nearby with its own signal still in range.
Passing a key to someone else
When the new spare is meant for a specific person rather than a drawer, such as a family member at another address or a regular caretaker for the vehicle, it is worth agreeing at handover what that person's key is expected to do and what happens if their circumstances change, such as no longer needing access. On some vehicles, removing one person's key later means the immobilizer's whole key memory is cleared and every remaining key has to be brought back and registered again, so it is worth knowing at handover whether that particular vehicle works that way.

What affects the quote
Aftermarket alarms or remote starters
A factory system wired into a third-party alarm or remote starter can add extra steps to programming, since the added equipment sometimes changes how the vehicle's module responds during enrolment.
Getting to the vehicle
Straightforward access, such as a driveway or an open lot, is simpler than a locked underground garage, a gated lot or a vehicle parked somewhere with restricted entry, which the quote accounts for.
Fob battery and physical condition
A fob that needs a fresh battery or shows cracking or water exposure adds a small amount of extra work beyond programming a key that is otherwise in good shape.
What to have ready
- Where is the vehicle usually parked?
- Do you know the VIN, or can you access the door jamb?
- Has a key ever gone missing that was never accounted for?
Spare Car Key Duplication: questions
QuestionsWill the spare include the remote buttons?
If the original has remote buttons and you want the spare to match, yes: the new key or fob is programmed to the vehicle's receiver so locking, unlocking and any other remote function respond the same way from either key. If a simpler spare is preferred instead, the remote portion can be left out while the chip that starts the car is still fully recognized.
Can a spare be made from a key that is already worn?
Yes, and it is often a good reason to make one. Rather than tracing every rounded edge of a worn blade onto the new copy, the locksmith can decode the lock or cut to a valid factory code for the blade, then read or clone the chip data separately for the electronics, producing a spare that is cleaner than the original rather than a copy of its wear. The worn key can then be compared against the fresh one and retired if it is due for that.
Can spare keys be made for older vehicles without a chip?
Yes, and it is usually the most straightforward version of this service. A vehicle old enough to use a plain mechanical key has no chip to read or program, so the whole job is cutting a matching blade, either traced from the original or cut to code, and testing it in every lock the first key opens.
