Spare Car Key Duplication in Lisgar
The blade on the everyday key has gone shiny and thin along one edge, and lately it needs a wiggle before the ignition catches.
In plain words
Households with more than one driver and one car key end up trading it back and forth, which works until two people need the vehicle at once. Making a second key from the original lets each driver carry their own, cut from the same blade profile and carrying the same chip or code the immobilizer recognizes, so neither key behaves differently from the other. The locksmith tests both apart from each other in the doors and the ignition before handing them back, and a family running two vehicles on the same lock family can sometimes be brought onto one key altogether.
How the visit goesA teenager just passed a driving test and reasonably wants a key of their own rather than negotiating over the family's single copy every time the car is needed. Two drivers and one key keep colliding on the same schedule.

How the visit goes
Locating the right blank
A correct spare starts with the correct blank: the same blade profile as the original, and where relevant the same shell shape for a remote head or proximity fob so the buttons and battery compartment line up. Aftermarket blanks exist for most common platforms, while a less common or very recent model sometimes calls for a shell sourced specifically for that vehicle. Getting this step right avoids a mismatch discovered only after cutting has begun, and it is one of the reasons the vehicle's year, make and model are confirmed early rather than assumed from the look of the current key.
Building a spare for a worn original
A key that turns with a wiggle or a fob with a soft button is not traced fault and all; instead the locksmith decodes the lock or cuts to a valid factory code for a clean blade, and separately reads or clones the chip data for the electronics, so the new key is built clean rather than inheriting the original's wear. Once the fresh key operates correctly, the worn original can be compared against it side by side, which often shows the household how much the daily key has degraded and helps decide whether it is time to retire it in favour of the newly made pair.
Keeping the household on one system
If the household runs more than one vehicle or more than one driver, this is a natural point to confirm every key still works the way it should: the original, the new spare, and any older keys already sitting in a drawer. A round of testing the whole set against the vehicle, rather than assuming a key still works because it once did, catches a fob with a fading battery or a blade that has quietly started to wear before it turns into a problem on a morning when someone is already running behind schedule.

What affects the quote
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.
Choosing a limited-function spare
A simplified key built for a valet or a specific driver, without every remote feature the primary key carries, generally involves less programming than matching every function exactly.
Timing around the day's other calls
A visit that fits between other scheduled stops is generally simpler to arrange than one needing a dedicated block of time set aside on its own.
What to have ready
- Do you currently have one working key, or more than one?
- What year, make and model is the vehicle?
- Where is the vehicle usually parked?
Spare Car Key Duplication: questions
QuestionsIs cloning the same as programming a new key?
They solve the same problem differently. Cloning copies the working key's existing code onto a new chip, which some vehicles' systems permit directly. Programming instead has the vehicle itself learn a brand-new code and accept it as an additional valid key, which is how most recent vehicles with rolling codes or added cryptography are handled, since their systems are built specifically to resist straightforward copying.
What if I have lost track of how many keys already exist for the car?
That is worth mentioning when you call, since it changes the plan. If the count is genuinely unknown, or a key was lost at some point and never accounted for, reprogramming the vehicle to accept only the keys currently in hand is often the sounder route, rather than adding a new spare on top of an uncertain set that might include a key nobody can locate anymore.
What testing happens before I leave with the new key?
Every door lock, the trunk or hatch, the ignition or start button, and any remote functions are checked with the new key on its own, apart from the original, so neither key is quietly helped along by the other's signal. The vehicle is started more than once to rule out an intermittent issue, and only once both keys pass independently is the visit considered finished.
