What Will Saab Ignition Key Replacement Be Like In 100 Years?

Saab Key Programming

Saab cars manufactured since 1994 have an immobilizer system based on coded keys. A new transponder is required for the addition of a second key, and special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.


It can be costly. This is the reason why you should always have a spare key on hand.

Transponder key

The transponder can be described as a key equipped with an electronic chip. saab key replacement nottingham transmits a signal when the key is inserted in the ignition. The car is able to check whether the signal is the same as the one on the key. If the signals match then the car will be able to unlock and begin. This is a great way to stop car theft and keep your car safe from thieves.

Transponder keys are a favored feature in automobiles, but you must be aware that they’re not as secure as traditional metal keys. While the metal parts of a traditional key could be cut and copied however, a transponder is secured by an electronic chip. This chip contains a unique code that is embedded into the car’s computer to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. However, it is only able to do this if your key fob has an unmodified chip that has been programmed to match. If not, the car will reject the key and refuse to start.

It’s essential to ensure that you have a spare key for your Saab. This is especially important especially if you live in a rural region that has numerous car thieves. You can obtain a replacement key for your Saab by going to the dealership without paying high prices. In the majority of instances, you can get a brand new key made right on the spot for less than half the cost of what you’d pay at a dealer.

Key for Wired

Saab cars typically come with two keys upon purchase. If you have only one, it is recommended to purchase an extra key fob as soon as possible since if you lose it the car will require a new CIM unit and the locking cylinders will need to be replaced. This can be costly, especially for used cars.

The next step is connecting the wires for columns and row to your microcontroller. This is the toughest part of the project and will require a lot of soldering. There isn’t a standard way to accomplish this, however it is essential to determine 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 includes 5 rows and 17 columns.

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

Sanabria states that a number of the tools sold in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 will assist customers who are shopping or DIY users to program replacement keys and restore immobilizer data. The tools connect to the OBD port and automatically guide the user through the procedure, making it simpler than replacing the computer in the vehicle.

Jump-starting the battery

A lot of people keep a set in their trunks to jump-start a vehicle in an emergency, but this might not be the best option for vehicles with newer technology. These vehicles have many electronic devices and computers that communicate with each other. A voltage surge when the battery is connected to another battery could damage the components making your car inoperable.

Start the working vehicle and allow it to run for approximately two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal on the battery that is good (it will have “POS” or “+” on it). Attach the other end of the black cable to an unpainted, clean metal surface underneath the car’s hood. The engine block would be a good choice. Do not connect the black cable to the negative terminal of the dead battery, since this could cause an ignition spark that ignites the gasoline in the engine bay.

After the cables have been connected, start the vehicle and let it run about five minutes. Then, disconnect them in reverse. The battery in the Saab 9-3 will charge while you drive. It will take a while for it to drop back down. You should purchase another key fob when you can. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement Case

Many Saab owners only have one key for their car and if they lose that key, it will cost them. It’s expensive to add an additional key and it requires replacing the CIM or TWICE for older models. In the event of theft, or other catastrophe, it is best to have an extra key. Even even if the key is “new” it won’t work.

The majority of locksmiths won’t be able to help in the event that you only have one working key, and the dealer will charge top dollar to replace the computer in your car to make a replacement. However, we can reset and re-program the computer’s EEPROM to prepare it to accept the new key without having to replace the entire system. This could save you a lot of money. It’s also a lot cheaper than waiting until you lose the only key.
