Saab Key Programming

saab ignition key replacement (click here to visit Pediascape for free) cars manufactured since 1994 feature an immobilizer system based on key codes. A new transponder is required for addition of an additional key, and special programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

The problem is that this can be very expensive. This is why it is important to always keep a spare key in your possession.

Transponder key

The transponder keys are keys equipped with an electronic chip. It transmits a signal to the car when it is put into the ignition. The car is able to check whether the signal is the same as the one on the key. If the signals match it will unlock and start. This is a great method to stop car theft and keep your vehicle secure from thieves.

Transponder keys are a popular feature in automobiles, however you must be aware that they are not as secure as traditional keys made of metal. While the metal portion of a conventional key can be cut and copied but a transponder key is protected by an electronic chip. The chip is a unique code that's programmed into the car's computer in order to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. The car will only recognize the key fob if it has an unmodified chip and has been programmed to match. Otherwise, the car would reject the key and refuse to start.

Key for Wired

Saab cars are usually provided with two keys. If you have only one, it is best to acquire an extra key fob as quickly as you can, because if you lose it, the car will require a new CIM unit and the locking cylinders will need to be replaced. This can be expensive especially for cars that are used.

The next step is connecting the wires for columns and row to your microcontroller. This is the most challenging part of the project and will require a good deal of soldering. There is no standard method to accomplish this, however it is important to think about the way you'll route and solder the columns and rows. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has 5 rows and 17 column.

Once the rows and columns are soldered, it's the time to connect them to key switches. To do this you must place a diode across each key switch pin and then solder it. This will shield the pins from current, preventing them from being shorted. A diode permits current to only flow in only one direction. It features a visual indicator of a black line that shows the direction in which the current will flow.

Some of the tools you can find at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- could assist customers at the shop or DIY users in some cases replace keys in the program and restore the lost immobilizer's data, Sanabria says. The tools plug into OBD ports and guide the user through each step which makes the process much easier than replacing the car's computer.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunk to use in an emergency, but jumping a battery on modern automobiles might not be the most efficient option. These vehicles are equipped with a number of electronic devices and computers that communicate with one another. A voltage spike when the battery is connected to another battery could fry these components and render your car unable to drive.

Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block would be an ideal choice. Do not connect the black cable to the negative terminal on the dead battery as it could ignite a spark that ignites the gasoline in the engine bay.

Once the cables are connected, start the vehicle that is disabled and allow it to run for around five minutes before disconnecting them in reverse order. The battery in your saab key battery 9-3 will recharge as you drive. It may take a while it to recharge again. It is recommended to purchase a second key fob, as soon as possible. The replacement of the one that works requires the installation and programming of a brand new computer chip.

Replacement case

Many saab key replacement cost owners have only one key for their vehicle and if they lose it, the cost will be. The reason for this is that it's not inexpensive to buy a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It's best to have a backup key in the event of theft or other disaster, and the best way is to purchase an additional key as quickly as you can. But don't buy a used key, even when it's "new." Claimed-new keys from aftermarket sellers will not be effective and are almost guaranteed to fail at the critical moment.
