Car Key Replacement in Melbourne

At 24h Melbourne Locksmith, we can make car keys and remotes from scratch, on site by the roadside, for most makes and models of car. 99% of cars built after 1995 have an electronic immobiliser in them which requires a correctly programmed transponder key to start them. The transponder and immobiliser system are separate from your key and remote.

Cutting The Key

The basic procedure for making replacement keys for a car where all the originals have been lost all starts with the same steps.

  • Open the locked vehicle using the most appropriate method. This is always done without causing any damage.
  • Disassemble one or more of the locks. There may be the door, ignition, boot, petrol cap, glove box, spare wheel, roof racks, etc.
  • 80% of the info needed to cut the correct key can be gained from the disassembled lock/s. Determine the configuration of the correct key. The remaining 20% is gleamed thru experience, hard work, & expensive computer software.
  • Cut a test key on a low quality plain brass key blank only, using the most appropriate method and machine.
  • Test the key in all the locks, and adjust and re-cut the key as many times as necessary to get it 100% perfect.
  • Re-assemble the disassembled locks and parts and install back into the vehicle.
  • Cut 2 new keys/blades to the correct, specifications determined by the previous 6 steps. These keys/blades are high-quality nickel-silver key blanks that will be the end product given to the client.
  • Test those 2 keys/blades in all the locks mechanically. They should now mechanically function in the doors, ignition and any other locks in the car. It's worth noting at this point that if the key/blade is turned in the ignition, the car will not start. It still has no transponder.
  • Insert the correct, un-programmed transponders into the keys! There are currently about 150 different types of transponder chips used by today's car makers, that then still have to be programmed into the car.

Those are the first basic steps to make replacement car keys when all have been lost.  There are some exceptions to these basic steps with some cars being harder to generate keys for than others.

From here, the methods used to deliver the full product of a remote transponder key,  diverge depending on the manufacturer and the key & transponder used.

Diagnostic Programming

Broadly speaking, Diagnostic Programming is the use of a specialist computer tool to connect to the car’s security system through the OBD port, which is usually hidden somewhere under the dash.  There are many different Diagnostic Tools & procedures for many different cars and systems, and there is no single Diagnostic Tool that can program all keys & remotes to all cars. Once the appropriate Diagnostic Tool is connected, depending on the car, the Tool, and the type of system used, we have the ability to delete any lost keys & remotes, and program in new keys & remotes.

There is usually an additional digital security challenge like a system PIN code, or a timed security delay that has to be met before we can proceed with programming keys or remotes, and this varies for maker to maker, model to model, and even changes mid series in some cases.  Sometimes we will require you to get this info from the Dealer, and it may require your ID.

Diagnostic Programming is the most straight forward type of Transponder programming and therefore the cheapest. Providing all the conditions have been met regarding the correct key, correct chip, correct remote, correct PIN code, correct Tool, full battery,  alignment of the planets, correct star sign,  angle of the sun relative to the horizon at midday in your latitude,  then it is relatively easy to follow the onscreen prompts of the Diagnostic Tool to generate replacement keys to the car.

Not all cars can have keys Diagnostically programmed into them. Some cars require other methods of programming, such as EEPROM or Chicken Dance.

EEPROM Programming

EEPROM stands for Electrically Erasable Programmable Read-Only Memory, a type of computer chip used in a wide variety of modern electronics. More about the general use can be read here, but for the purpose of this discussion, it’s a method of correctly programming the car and/or the transponder chip so that the car will start when you turn the key.

EEPROM programing for a modern car first involves finding the car’s ECU, which could be in the instrument cluster, under the dash, or absolutely anywhere else depending on the make and model of the car. After locating the ECU, removing it can be  easy or hard depending on where it is installed.  With some models of car,  a professional mechanic’s skills and a couple of hours of his labor are needed to remove the ECU. Once the ECU is out, it’s usually best to work on it in a static sterile environment, such as on an electronics bench under a big magnifying glass.

The EEPROM chip is located somewhere on the main circuit board, and depending on the board, system & chip, it might have to be de-soldered from the board to be read, or may be able to be read in circuit with specialized electronic equipment and teeny tiny little clamps.  The info on the EEPROM chip is either modified to suit the new keys/transponders or the data from that EEPROM chip is copied into the new keys / transponders. If necessary the EEPROM chip is then re-soldered back onto the ECU,  the ECU is installed back into the car, and the rest of the car is re-assembled.

Remote Programming

In some cars, the remotes for the central locking or alarm system are programmed during the Diagnostic or EEPROM process. For those cars that do not use these processes to program the remotes, they usually have the remote programmed by “chicken dance”.  Each make, model and year has its own proprietary chicken dance, and you have to perform all the correct steps in the correct order to successfully program the remote.

An example of a chicken dance might be:

  • Put the key in & out of the ignition 3 times quickly.
  • Open and shut the driver's door 4 times quickly.
  • Scratch your left eyebrow with your right hand.
  • Flick the rear demister 5 times.
  • Turn the ignition to Accessories.
  • Whisper the sacred text to Odin.
  • Press and hold the button on the new remote.
car keys

There are many many different types of car remote, with them differing in size, shape, color, number of buttons, frequency transmitted, etc. A great number of cars now have Remote Flip Keys, with all the components mounted into a single handy unit housing the key, remote, & transponder all in one trendy cover that flips out the key when pushed. These flip keys started in the early 2000 European cars, but now can be found across all manufacturers. Some cars require an OEM (Factory Original) Remote to be used, so the client cannot have any choice in the  colors, shapes or style, and has to use what the manufacturer dictates. Other cars can use aftermarket alternatives with a wide variety of choice in configurations, styles, and colors.

Proximity & Smart Keys

An ever-growing proportion of cars on the road today have Proximity or Smart Keys and the feature of push button start. This is where the car has sensors that detect the correct key when it’s close by and allows entry & starting of the car. You don’t even have to take the key out of your pocket.

It’s important to note that even though they may be hidden, ALL of these cars have mechanical key locks in the door and usually also under the push button start. This is for mechanical override in the event of a fault in the car or a flat battery in either the car or the key. To make car keys for a car with a proximity key system, the basic steps are still the same to make the mechanical keys. Transponders and remotes are usually programmed via the Diagnostic method of car key replacement in Melbourne, but not always.

Most Proximity & Smart Keys have to use OEM equipment, although there are a number of new aftermarket options available this year.

  • What Information We Need
Every make and model is different, with different blades, remotes and transponders across models and years. For this reason, we need the full details of the car in order to accurately quote you. We can get the full info of the car through a number of ways. The easiest way is to give us the License Plate number if the car is registered with Vic Roads. From this link, we can get the VIN, which we can use to identify the make, model, year and month of the individual car. Simply call us with the License Plate or VIN for a fast accurate quote.

Modern Car Keys and Components

Since the early 90s, most vehicles come with quite sophisticated security features, incorporating electronic immobilizers, high security locks, and central locking systems. Modern car keys have also become very sophisticated to match. As well as the traditional key blade that varies widely in type and security level, the modern car key can also have a remote control for the central locking, a transponder chip, and possibly even a touch screen! 

We shall examine in detail the 3 main components that make up a modern car key. Only if you have an all metal key, with no plastic at all on it: AND it actually starts the car, only then can you be assured that you don’t have a car with an immobilizer that requires a transponder within your key. Continue reading for more information about each of the 3 main modern car key characteristics.

Your car key may not have all 3 of these components, but if you own a vehicle that was built after 1995, then you can almost guarantee that the vehicle has an electronic immobiliser and the key is a transponder key. There are a few exceptions (some trucks and industrial vehicles), but they are very rare. Even if your key has no visible electronics, but has a plastic head, chances are that is has a chip hidden within the plastic head.
