Car Key Fobs Explained
Most modern vehicles on the Sunshine Coast now use a car key fob. From our conversations with our customers, we find that most drivers are unsure how their fob works, what to do when they stop working, or whether they can be replaced without going to their local dealership or mechanic. At Sunny Coast Car Keys, we replace, program, and repair car key fobs every day across the Sunshine Coast from Caloundra to Noosa and up to Gympie.
If your key fob is lost, damaged, or no longer unlocking or starting your car, we explain what a fob is, how it works, and how we can help you get back on the road quickly.
What Is a Car Key Fob?
A car key fob is a small electronic remote that allows you to unlock, lock, and depending on your make and model, start your vehicle without inserting a traditional metal key. Most fobs communicate wirelessly with your car using coded signals that are unique to your vehicle.
Depending on the make and model, a key fob may control door locking, boot access, alarm systems, and push button start functions. For security, vehicles will not start unless the correct programmed fob is present.
Types of Car Key Fobs on the Sunshine Coast
Modern vehicles use different types of car key fobs depending on the age, make, and technology of the vehicle. Understanding which type of fob your car uses helps explain why replacement costs, programming time, and security features can vary.
Basic Remote Key Fobs
Basic remote key fobs are typically found in older vehicles and entry level models. These fobs are used mainly to lock and unlock the doors and activate or deactivate the vehicle’s alarm. The engine is still started using a traditional metal key inserted into the ignition.
While these fobs are simpler than newer systems, they still need to be correctly programmed to communicate with your vehicle. If the remote stops working, the issue is often a flat battery, worn buttons, or internal electronic failure.
Integrated Remote Keys
Integrated remote keys combine a traditional metal key blade with built in remote buttons. This style is very common in Australian vehicles and is used across brands such as Toyota, Mazda, Hyundai, Ford, Holden, Kia, and Nissan.
The metal key is used to start the vehicle, while the buttons control locking, unlocking, and sometimes the boot. Inside the key is a transponder chip that must be programmed to the car. Without correct programming, the engine will not start even if the key physically turns in the ignition.
Replacing this type of key requires both cutting the blade correctly and programming the electronic components to the vehicle’s immobiliser system.
Smart Key Fobs and Proximity Keys
Smart key fobs, also known as proximity keys, are used in many newer vehicles and luxury models. These keys allow the car to unlock automatically when the fob is nearby and enable push button start without inserting a key.
Because these systems rely on encrypted signals and advanced security features, smart key fobs are more complex to replace. Programming must be done using specialised diagnostic equipment that communicates directly with the vehicle’s computer.
If a smart key is lost or stolen, it is often possible to remove the old key from the system so it can no longer start the car. This is an important security step and something many drivers are not aware can be done.
Why the Type of Key Fob Matters
Each type of car key fob uses different technology, security levels, and programming methods. This is why key replacement costs and timeframes can vary between vehicles.
At Sunny Coast Car Keys, we identify the exact type of key your vehicle uses before starting the job. This ensures the replacement key fob is correctly programmed, secure, and fully functional from the moment you drive away.

What Happens When a Key Fob Stops Working?
When a key fob stops responding, a flat battery is usually the problem. However in some cases, the circuit board and coded transponder chip that communicates with your vehicle’s immobiliser system can fail. If any part of that communication stops, the vehicle will not unlock or start.
Key fobs often stop working due to internal electronic damage caused by drops, moisture exposure, or general wear over time. Even a small crack in the casing can allow moisture to damage electronic components. In some cases the fob itself is still functional but has lost synchronisation with the vehicle, meaning the coded signal is no longer being recognised.
When a fob has fully failed, replacement and reprogramming is required. Our mobile locksmiths assess the issue on site, test the fob, and determine whether it can be repaired, resynchronised, or needs to be replaced. This allows us to recommend the most cost effective solution rather than replacing parts unnecessarily.
Replacing a Key Fob Without the Original
Losing your only key fob does not automatically mean a tow to your dealership or mechanic. In most cases, we can program a new key fob even when the original is missing.
Using specialised diagnostic equipment, we access the vehicle’s computer to program a new fob and pair it with the immobiliser. Where possible, we can also remove lost or stolen keys from the vehicle memory so they can no longer unlock or start your vehicle. This is useful if you believe your keys were stolen or lost in a public space. This is an important security step that many vehicle owners are unaware is available.
The ability to replace a fob without the original depends on the vehicle make, model, and year. We confirm this before starting the job so there are no surprises.
Key Fob Replacement Versus Dealership Costs
Dealership key replacement is often more expensive due to labour rates, booking delays, and limited key stock. Vehicles are usually required to be dropped off, and wait times can stretch from several days to weeks.
As a mobile automotive locksmith, Sunny Coast Car Keys brings the required equipment directly to your location. This removes towing costs, reduces downtime, and allows most key fobs to be replaced and programmed the same day. For many vehicles, this results in a faster and more affordable solution compared to dealership replacement.
