In this article written for The Locksmith journal, Michael uses his expert knowledge to clarify many of the points often raised by our readers concerning cloning. In the last issue of The Locksmith journal, Nicky at NW Keys produced a great article comparing the various types of key cloners on the market and a basic FAQ surrounding cloning. This time, I want to take a bit more in-depth look at how cloning actually works, and what it can mean for the locksmith or shoe repairer who has always been put off by cloning. Many who want to start as auto locksmiths like to cut their teeth on key cloning as it is a relatively cheap area of the market to get into. A big percentage of this market can also be covered with the most basic hardware, and the procedures are largely independent of vehicle manufacturers – all factors that can get more complicated when you get into new vehicle key and remote programming. Background Knowledge All auto locksmiths will be fully proficient in understanding how vehicle security systems work, but for those from a domestic and commercial side there can be an element of ‘black magic’ that I can hopefully expand on here to help provide a clear understanding. Since 1996, in an attempt to reduce vehicular theft, 64 THE SEP/OCT 2014 ISSUE SPONSORED BY ADVANCED KEYS auto manufacturers started including small computer chips, called ‘transponders’ , inside the key that communicate with the vehicle to allow it to switch off the immobiliser. Importantly, these transponders are powered directly from the vehicle itself, and are typically hermetically sealed in either epoxy or glass - making them highly reliable and resistant to environmental factors such as temperature, shock and humidity. The technology worked so well that it resulted in vehicular thefts plummeting almost overnight. While that may have proved to be good news for consumers, it also meant that auto locksmiths had to upskill in order to read, program, write and understand how these chips work, in order to make up a new set of keys for the customer. Getting into cloning allows the non-auto locksmith to start understanding the range of transponders available and their applications on vehicles. How cloning works Cloning car keys is very much ‘does what it says on the tin; it is taking the customer’s original key, and copying the data onto a new transponder so that it is an identical match to the original. The vehicle cannot tell the difference and so both keys are allowed to start the engine. While it sounds fairly straightforward, different types of transponder have different methods of cloning them and will clone onto either the same type of transponder, or a new ‘cloning type’ will be needed to accept the data. The pros and cons around cloning Some of the benefits to cloning car keys are: • Easy and quick – it is a simple process of read, remove, write (for certain transponders) - it can actually take longer to cut the key blank! • Cheap – from both a customer and locksmith perspective, you don’t need lock picks or a wide range of remotes, just a handful of transponders, a cloning device and the usual key blanks and key machine. • No changes to the vehicle – whenever you plug in key programming equipment to the vehicle you can be reading, writing and clearing fault codes from all over the vehicle and customers can potentially blame you for all sorts of weird technical gremlins ‘that never happened before you came out!’ • Access – as above, to clone most transponders you do not even need the vehicle to be there so access to the shop is not essential. You can be stuck in the middle of a field at a car boot sale and still clone car keys! Negatives: • Lost key situations are a nogo for any cloning only auto locksmiths as obviously you have nothing to clone from. • Remote options – there are some options from Bianchi that will allow you to clone remot
