saab centre milton keynes Key Programming

Saab cars built since 1994 utilize an immobilizer system based on key codes. A new transponder is required for the addition of an extra key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The problem is that this could be quite costly. This is why you should always keep a spare key in your possession.

Transponder key

The transponder key is a key with an electronic chip that sends a signal back to the car when it is placed in the ignition. The car then analyzes the signal to see whether it is identical to the one that is in the key. If the signals are identical the car will be able to unlock itself and start. This is a great method to stop auto theft and keep your vehicle secure from thieves.

Transponder keys are a favored feature in vehicles, but you should be aware they aren't as secure as classic metal keys. The metal portion of a traditional key can easily be cut and copied, whereas transponders are protected by an electronic chip that guards it. This chip contains an unique code that is inserted into a car's computer order to identify it.

The car will recognize the Saab keyfob and allow it to turn on. However, it can only do this if the fob is equipped with a chip that is not modified that has been programmed to match. In the absence of that, the car will reject the key and won't start.

It's important to make sure that you have a spare key for your Saab. This is particularly important when you live in a rural location where there are a lot of car burglars. You can get a new key for your Saab ignition key Replacement by visiting the dealership without paying high prices. In the majority of instances, you can get an original key made on the spot at a fraction of the cost of what you'd pay at the dealer.

Wired key

Saab cars are usually supplied with two keys. If you only have one, you need to purchase an extra key as soon as you can. This is because if the key is lost, the car will need an entirely new CIM and the locking cylinders replaced. This can be costly especially for used vehicles.

The next step is to connect the wires for columns and row to your microcontroller. This is the most difficult part of the project and requires a significant amount of soldering. It's not a common way to go about it, but you need to plan how to route and solder each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.

Once the rows and columns are soldered, it's the time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the pins on the key switch from current and stop them from being shorted. A diode lets current only flow in one direction. It features a visual indicator that is black, that indicates which direction current will flow.

Sanabria states that a number of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO and IM508 will assist customers who are shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into OBD ports and help the customer through each step which makes the process much easier than replacing the car's computer.

Jumpstarting the battery

The majority of people have a set of jumper cables in their trunks in case of emergency however, jumping a battery in newer vehicles may not be the best choice. These vehicles are equipped with numerous digital and computers that communicate with each other. A voltage spike when a battery is connected to another one could cause damage to the parts, rendering your car undriveable.

Start the working vehicle and saab ignition key replacement let it run for about two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end to a clear, unpainted metal surface underneath the hood of the disabled car. The engine block is a great alternative. Don't connect the black cable to the negative terminal of the dead battery, since it could spark an ignition that ignites the gasoline in the engine bay.

After the cables have been connected, you can begin the car and let it run for approximately five minutes. Then, disconnect them in reverse. Keep in mind that the battery on your saab key fob 9-3 is charged when you drive, so it may take some time for the battery to go back down again. It is a good idea to purchase a spare fob as soon as you can, because replacing the one that works requires the installation of a brand new computer module and a special program to convince it that your missing keys aren't trying to steal the car.

Replacement case

Many Saab owners have only one key for their car and if they lose it, they'll be charged. The reason is that it's not inexpensive to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's best to have a spare key in the event of theft or any other catastrophe and the best option is to buy an extra key as early as you can. Don't purchase a used key, even if it's "new." Keys that are claimed-new from aftermarket sellers will not perform and are almost certain to fail in the crucial moment.

The dealer will charge you top dollar for only one working key. However, we can reset and re-program the computer's EEPROM to prepare it to accept the new key, without replacing the entire system. That can save you lots of money. It's also much less expensive than waiting until you lose the only key.
