saab replacement keys cars built since about 1994 feature an immobilizer mechanism based on coded keys. A new transponder is required in order to enable the addition of an additional key, as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

It can be costly. This is why it is important to always have a spare key at hand.

Transponder key

The transponder is a type of key with an electronic chip. The chip transmits a signal when the key is inserted in the ignition. The car checks to see whether the signal matches with the one on the key. If both signals match it will open itself and start. This is a great way to protect your car from theft.

Transponder keys are a popular feature in vehicles, but you should be aware they are not as secure as traditional metal keys. While the metal part of a conventional key can be cut and copied, a transponder is protected by an electronic chip. This chip contains a unique code that is programmed into the car's computer to identify it.

When a saab 9-3 key replacement key fob is used, the car recognizes it and allows it to turn on. However, it will only do this if the key fob has an unmodified chip that has been programmed to match. If not, the car will reject the key and not start.

Saab cars typically come with two keys upon purchase. If you only have one, you should purchase an additional key as fast as you can. This is because if it's lost the car will require an entirely new CIM and the locking cylinders replaced. This could be expensive especially if you're purchasing a used car.

The next step is to connect the column and row wires to the microcontroller. This is the most tedious part of the project and it will require a lot of soldering. There's no standard way to accomplish this, but it's important to plan out the route you'll take and solder the columns and rows. There are 22 microcontroller wires and pins that you can connect to this keyboard. It includes 5 rows and 17 column.

After the rows and column are joined, it is time to connect the key switches. To do this you must place a diode on each key switch pin and solder it. This will shield the pins from current and prevent them from getting shorted. A diode permits current to only flow in one direction. It comes with a visual indicator with a black band that indicates which direction current will flow.

Some of the tools offered at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- can aid shop customers or DIY customers in certain cases program replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into the OBD port and automatically guide the user through the process, making it easier than replacing the computer in the vehicle.

Jumpstarting the battery

Most people keep a few sets of jumper cables in their trunk in case of emergency, but jumping a battery in newer vehicles may not be the best choice. These cars have a variety of computers and digital devices that communicate with one another. A voltage spike when the battery is connected to another one could cause damage to the parts making your car unusable.

Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged vehicle's hood. An engine block is an ideal choice. Don't connect the black cable to the negative terminal of the dead battery, since it could ignite a spark that ignites the gasoline in the engine bay.

The battery in the saab key replacement cost 9-3 will charge as you drive. It takes a while for it to recharge again. You should consider purchasing another key fob as soon as you can.

Replacement case

Many Saab owners have only one key for their vehicle and if they lose that the cost will be. 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 is recommended to have a second key in case of theft or other disaster, and the best way is to buy an extra key as soon as you are able to. Even it's "new", it will not function.

The majority of locksmiths won't be able to help when you only have one working key, and the dealer will charge high prices to replace the computer in your vehicle to make a replacement.
