Are your car keys giving you trouble? Are you still having problems after you’ve replaced the key’s batteries? Then it might be time to get a new set of car keys.
You might be having some questions about replacing your car keys.
Let’s take a look at some of the frequently asked questions when replacing car keys.
Older car model keys that do not have any electronics.
If your car was not manufactured in the last 20 years then you can regard your car as an older model.
These car models’ doors usually open manually with a metal key.
The great news is that you don’t need a key for a locksmith to cut a new copy for you.
If you live in Toronto, Ontario, then The GTA Lockman is the company to call when you need a new pair of keys.

Most vehicles manufactured in the last 25 years use an electronic immobiliser as a standard security feature. The immobiliser is a system built into your car that prevents the engine from starting unless it receives a matching signal from the key. That signal comes from a small transponder chip embedded inside the key head or fob.
When a new key is cut, the physical blade may fit the door and ignition locks perfectly, but the car will not start without the chip being programmed to match the vehicle’s immobiliser code. This process is called car key programming. It requires specialist automotive software and the correct diagnostic hardware to communicate with the car’s onboard computer.
Without programming, a correctly cut key will turn in the ignition but the engine will either crank without starting or shut off professionally after. This is a common source of confusion for vehicle owners who have had a key cut at a hardware store or online retailer — the key looks right and fits the lock, but the car will not respond.
GTA Lockman carries up-to-date key programming tools that cover most domestic and imported vehicle makes. Our mobile automotive locksmiths come to your location and complete the programming on-site, so there is no need to arrange a tow or wait at a dealership service bay.
Car key programming covers several different systems depending on how your vehicle communicates with its key. Here is what each service involves and when you would need it.
Transponder keys contain a passive radio frequency chip that sends a unique code to the car’s receiver every time the key is inserted into the ignition. The car will only start when the received code matches what is stored in the immobiliser module. We programme transponder chips using dedicated automotive tools, pairing them precisely to your vehicle’s system. This service is required for new keys, replacement keys, and spare keys on most vehicles made after 1998.
Key fobs communicate with your vehicle’s central locking system via radio frequency. When a fob loses its pairing, the lock and unlock buttons stop working even though the physical key may still operate the ignition. Fob re-programming restores the wireless connection between the remote and the car. We also supply and programme replacement fobs when the original is lost or damaged beyond repair.
Smart keys use proximity sensors to detect when the fob is inside the vehicle. Pressing the start button then signals the immobiliser and engine management system to allow the vehicle to run. Programming a smart key requires direct communication with multiple vehicle modules simultaneously. Our technicians use current-generation automotive programming software to pair push-to-start fobs to your car correctly.
Keyless entry remotes that control door locking independently of a blade key need to be paired to your specific vehicle’s receiver. This is a common request when a fob is replaced after being lost, after a battery change causes the pairing to drop, or when a second remote is needed for a new driver. We programme keyless entry remotes for most vehicle makes on-site at your location.
When a key is lost or stolen, simply getting a new one programmed is not always sufficient. If the lost key is still out there, it may still be recognised by your vehicle. Erasing all previously registered keys and re-programming a clean set removes that risk. This service is also useful when buying a used vehicle, as you cannot verify how many key copies the previous owner retained.
In some cases the immobiliser module itself needs to be reset or updated, particularly after a dead battery, an electrical fault, or a failed DIY programming attempt. GTA Lockman’s technicians can diagnose immobiliser faults and carry out the necessary reset procedures using manufacturer-level programming tools, restoring normal communication between the key and the vehicle’s engine management system.
Our automotive key programming service covers a wide range of domestic and imported vehicles. The list below includes the makes we work with most often, though our tools cover many additional models.
Not sure if we cover your vehicle? Call (647) 955-3277 with your make, model, and year and we will confirm before you book.
Dealerships are not the only option when you need a key programmed. An automotive locksmith with the right equipment can complete the same programming work at your location, often at a lower cost and with a reliableer turnaround.
GTA Lockman technicians use professional-grade programming software that covers the same vehicle communication protocols used by dealer service centres. The difference is that we are mobile, so we come to wherever your vehicle is parked rather than requiring you to transport it.
Dealers often replace full modules when a targeted programming fix will do. We charge only for the work your vehicle needs.
We come to your home, workplace, or parking location anywhere in Toronto and the GTA. No towing required.
All key programming work comes with a 12-month warranty. If the programming fails within that period, we return and fix it at no additional cost.
Every technician is licensed, insured, and able to provide identification on arrival. We verify ownership before any work begins.
Select a question below to read the answer.
For a small number of older vehicles, the manufacturer built a self-programming procedure into the car that the owner can follow using the existing key. This typically works only when you still have at least one working programmed key in your possession, and it covers basic key fob pairing rather than full transponder programming.
For most modern vehicles, owner self-programming is not possible. The immobiliser system requires a professional diagnostic tool that reads and writes data to the car’s engine control unit. Attempting to programme a key without the right equipment can sometimes lock the system and require a more involved reset to fix. For anything beyond a simple fob battery swap, calling a licensed automotive locksmith is the most reliable approach.
The time required depends on the vehicle make, model, and the type of key being programmed. A straightforward transponder key or remote fob programming for a common vehicle typically takes between 20 and 45 minutes once the technician is on-site. Push-to-start smart key programming can take a little longer, anywhere from 45 minutes to 90 minutes, because it involves communicating with multiple vehicle modules.
In some cases involving older or less common vehicles, the programming process may take additional time if the system requires a specific sequence or if an immobiliser reset is needed first. Our dispatch team will give you an estimated time range when you call based on your specific vehicle.
This is one of the most common signs of a transponder chip that is not correctly programmed or has lost its pairing with the vehicle. When the immobiliser does not receive the expected code from the key, it prevents the fuel system or starter circuit from activating. The key may turn freely because the mechanical cut is correct, while the electronic side is unrecognised.
Other symptoms of a programming issue include the immobiliser warning light staying on after the key is inserted, or the engine starting briefly and then shutting off. Both indicate that the transponder signal was not accepted. A diagnostic check with our programming tools will confirm whether this is the cause and allow us to re-programme the key on site.
Yes, in most cases we can programme a key blank or fob that you purchased elsewhere, provided it is compatible with your vehicle. Before booking, it helps to check that the part number or compatibility details on the key you bought match your vehicle’s make, model, and year.
Some aftermarket blanks are not fully compatible with certain vehicle systems, which can cause issues during programming. If you are unsure, call us before purchasing and we can advise on what to look for. We also carry a stock of blanks for most common vehicles, so if your purchased key turns out to be incompatible, we can usually supply a suitable one at the time of the visit.
It depends on your situation. If you are simply adding a spare key and all existing keys are still in your possession and working correctly, there is no need to erase the old ones. Adding a new key to the system without erasing the others is a straightforward process.
If a key has been lost or stolen, erasing all previously registered keys and programming a fresh set is a sensible step. It removes access for whoever may have found or taken the original key. This is also worth considering when purchasing a used vehicle, since you cannot confirm how many key copies exist from the previous owner. GTA Lockman can perform a full key memory clear and re-programme your chosen set of keys during a single visit.
