Features to look out for when buying a Car Key Programmer

Car key programmers contain many features today. However, depending on the model you buy, the level of features will vary. Budget options will generally focus on programming new keys for the door locks and ignition.

More advanced key programming devices will allow you to control, reset, and program the vehicle’s immobilizer as well as run diagnostic checks on the overall security alarm system.

Here is an example of some of the features you can expect to find on a modern car key programmer.

  • Add a key/ new key programming – This is the primary function of all car key programmers. This will allow you to create a new key for the car from a blank key. The same code will be used that exists on your current or missing key.
  • Reset/relearn keys – This function is useful if your existing keys have malfunctioned. Using this feature you will be able to reset the key to the factory setting, and therefore ready to program.
  • Remote control programming – Replacement remote controls and key fobs are programmed using this feature. The device will insert the relevant code into the remote control so that it is compatible with your vehicle.
  • Key cloning – If your aim is to make a clone of one of your existing keys, this function will do it quickly and efficiently.
  • Read keys from IMMO memory – This allows you to generate new keys using information stored in the vehicle’s memory. In cases where all originals are lost, you will be able to use this function to create a new key from a blank.
  • All keys replace – This feature will allow a complete reset of the vehicle’s coded entry system while producing new keys with the new code. All old keys will be deactivated using this method.
  • PIN code reading – This function gives you access to the vehicle IMMO system. This is where the PIN used to gains access to your car is stored.
  • Reset immobilizer – If you are having issues with your immobilizer, you can use an applicable car key programmer to gain access to reset and/or troubleshoot the issue. You can also force the immobilizer to recognize new keys with this feature.
  • Program immobilizer – This is an advanced feature that allows you to program the IMMO. It provides comprehensive control of the vehicle’s electronic security. With this, you essentially have “factory floor” access to the security system, allowing you to change parameters and even switch it off.

Car Key Programming  – A little background and how to use them

Car key programming is one of the first skills an auto locksmith has to master. This does not mean that the average non-skilled consumer cannot attempt to program themselves, however.

A wide range of vehicles are now covered with the most basic hardware, that is available at reasonable prices.

Our 5 car key programmers reviewed above are a good example of that. These tools are sold independent of vehicle manufacturers, yet are designed to be compatible across a range of brands.

So how did we get to where we are now with car key programmers?

The introduction of the vehicle transponder

The transponder was first introduced into vehicle security back in 1996.

Manufacturers across the globe (affordable, low-budget offerings right up to supercars) started fitting small computer chips into the key that would communicate with the car telling it to switch the immobilizer off.

The impact on car crime was immediate. It was much harder for criminals to steal a vehicle now.

With the transponder receivers being hermetically sealed inside the car, the reliability of the system was and still is excellent.

All of this meant that auto-locksmiths (and in turn the consumer) had to step up their skillset in situations where keys were lost or damaged.

Car key programming leads to a full understanding of the range of transponders available and their applications on vehicles.

Car Key Programming

Car key programming using a diagnostics tool is a very popular method with auto-locksmiths, mechanics, and now the general vehicle owner at home.

In many ways, this has become the most used method of car key programming due to the fact automobile keys are so much more complicated today.

The codes that are created to communicate and sync with a transponder contain a trillion possible combinations.

This is required so that the ‘tech thief’, a car criminal armed with a laptop and programmer, cannot steal a vehicle while it is parked outside your house.

To increase security protocols further, some vehicle security systems require a 20-digit PIN code.

Not only is that extremely difficult to hack, but these codes are also synced between vehicle and key and are automatically wiped and changed each time the car is switched on.

Needless to say, the car key programmer is vital if you are to control this process and create a new workable key for your car.

Using the Car Key Programmer

Programming using a diagnostic tool is made simple as the programmer will do all the technical work for you, (well mostly).

The programmer is able to sync the new key and vehicle together by using a small series of commands, (these, of course, differ depending on the tool you are using).

The tool will then program both vehicle and key so that the initial start-up code is the same.

This is enough to allow entry into the vehicle where further, more in-depth programming can be carried out once access to the vehicle ignition is acquired.

All of the tools reviewed above contain instructions on how to use the programmer to gain access to your vehicle (assuming it is compatible).

However, in situations where you are unable to get the programmer to work, an auto-locksmith or specialist shop service is definitely advised.
