What is an immobiliser? An immobiliser is an electronic security device which stops a vehicle from being started unless the correct digital key or token is present. In other words, the car can only be started with its key, and hotwiring it would be no use. On a mechanical level, immobilisers work by disabling at least two of the three main components which make your vehicle move, namely the ignition, fuel system and starter motor. Disabling two of these things will prevent a vehicle from starting. When you put your key in the ignition, a code is sent from a transponder in the key itself to the vehicle’s electronic control unit (ECU), often via a receiver in the steering column. The method will vary from one manufacturer to another, but they all work on the premise that the vehicle will only start if the key’s code matches that of the ECU. The inner-workings of these devices understandably aren’t widely publicised as this would give thieves the chance to get the upper hand. Do I have one? Factory-fitted immobilisers have been mandatory on all new cars since 1998, so if your car was built after then, it’ll almost definitely have one – unless a previous owner has done some tinkering with it and disabled or removed it. There may be some pre-1998 vehicles with factory-fitted immobilisers, but you’ll have to check your owner’s manual to be sure. Also, some older vehicles may have had an immobiliser retrofitted after they’ve left the factory. Are all immobilisers the same? Their function is the broadly the same, and their mechanisms may vary, but they’re organised into categories, with some immobilisers rated as more secure than others. The Thatcham Motor Insurance Repair Research Centre is a not-for-profit research organisation concerned with safety and security equipment in the automotive industry. You may have seen or heard the phrase Thatcham-approved alarm, or immobiliser, for example. You can see how Thatcham rates your car’s security here Is it worth having one? Having a factory-fitted, Thatcham-approved immobiliser will make your car more secure than a car without one. This should be reflected in cheaper car insurance premiums. If your car doesn’t have one and you’re thinking of installing one, you should make sure it’s a Thatcham-approved device. But an immobiliser isn’t your only security option, as there are other Thatcham-approved devices you can install to keep thieves at bay while lowering your premiums. Thatcham-approved steering wheel locks, for example, may be a cheaper option. Of course the best way to secure your vehicle is to keep it in a locked garage, if possible, when you’re not using it. |

That is why you have a valet key with the car. The one without the plastic covering on it. |

If your original car key has a chip in it, a $ 4 or $ 5 replacement key made at K-Mart or wherever will not work. The valet key will start your car but won't open the trunk or glove box. A key with a chip in it costs about $ 75 and up. We have keys made all the time for repos. There actually is a way to override the chips but I won't even hint at was it entails. It is NOT a simple fix, by any means. Sometimes we have keys made, knowing they won't start the car but at least we can put it in neutral and steer it to get it out of a tight parking spot. I don't know which cars have chips, but the key maker usually knows and tells us ahead of time. |

Immobilisers have been mandatory in all new cars sold in Germany since 1 January 1998, in the United Kingdom since 1 October 1998, in Finland since 1998, in Australia since 2001 and in Canada since 2007. Early models used a static code in the ignition key (or key fob) which was recognised by an RFID loop around the lock barrel and checked against the vehicle's engine control unit (ECU) for a match. If the code is unrecognised, the ECU will not allow fuel to flow and ignition to take place. Later models use rolling codes or advanced cryptography to defeat copying of the code from the key or ECU. |
