10 Inspiring Images About Saab Ignition Key Replacement
Saab Key Programming
Saab cars made from 1994 have an immobilizer system that is based on a set of keys. The addition of a key requires a new transponder, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
This can be expensive. It is always advisable to keep a spare set of keys in your possession.
Transponder key
The transponder is a type of key that has an electronic chip. The chip sends a signal when the key is put into the ignition. The car then checks the signal to determine whether it is the same as that of the key. If the signals are in sync the car will then unlock and begin. This is a great way to deter car theft and keep your vehicle secure from thieves.
Transponder keys are an increasingly popular feature in automobiles, however it is important to know that they are not as secure as classic metal keys. The metal part of the traditional key can be easily copied and cut, but transponders are protected by an electronic chip that safeguards it. This chip contains an unique code that is programmed into the car's computer to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. But, it's only able to do this if your key fob has an unmodified chip that has been programmed to match the original. The car won't start when the key isn't programmed to match.
It is essential to ensure that you have a spare key for your Saab. This is especially important when you live in a rural region that has numerous car thieves. The good thing is that you can obtain a replacement key for your Saab without needing to visit an auto dealership and pay the high costs that they demand. You can get a replacement key created on the spot for less than half the price you'd pay at a dealership.
Wired key
Saab cars typically come with two keys when they are new. If you only have one, it's a good idea to get an extra key fob as soon as is possible in case you lose it, the car will require the replacement of a CIM unit and the locking cylinders will have to be replaced. This can be expensive especially for cars that are used.
The next step is to connect the wires of the column and row to the microcontroller. This is the most difficult part of the project and will require a large amount of soldering. There is no standardized way to accomplish this, but it's important to plan out how you will route and solder the columns and rows. There are 22 microcontroller wires and pins that you can connect for this keyboard. It has five rows and 17 column.
After the columns and rows are joined then it's time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins on the key switch from current and keep them from being shorted. The diode will only allow current to flow in one direction, and it also has a an indicator in black that shows the direction in which current will flow.
Sanabria states that a number of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 will assist customers who are shopping or DIY users to program replacement keys and restore immobilizer data. The tools plug into the OBD port and automatically guide the user through the process, making it easier than replacing the computer inside the vehicle.
Jumpstarting the battery
The majority of people have the set in their trunks to jump-start a car in case of emergency, but it might not be the best option for vehicles with newer technology. These vehicles are equipped with a number of digital and computer systems that communicate with each other. A voltage spike when the battery is connected to another battery could damage the components making your car unusable.
Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach saab 93 key programming to a clean, unpainted metal surface beneath the hood of the disabled car. The engine block is a good option. Don't connect the black cable to the negative terminal of the dead battery, as this could cause an ignition that ignites the gasoline in the engine bay.
Once the cables are connected, turn on the vehicle that has been disabled and let it run for approximately five minutes before disconnecting the cables in reverse order. Remember that the battery on your Saab 9-3 is recharged during your drive, which means it could take a while for the battery to go back to normal. It's a good idea to buy a spare key fob as soon as you can, because replacing the only functioning one requires the installation of a new computer module and special programming to convince the system that your lost keys aren't attempting to steal the car.
Replacement case
Many Saab owners have only one key for their car and if they lose that the cost will be. The reason for this is that it's not cheap to replace a key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It is recommended to have a backup key in case of theft or any other catastrophe and the most effective way is to purchase a second key as quickly as you can. Don't purchase a used key, even the case that it's "new." Keys that are claimed as new from a second-hand store will not work and are likely to fail at the critical moment.
The dealer will charge the highest dollars if you only have one working key. We can, however, reset and re-program the computer's EEPROM to accept the new key without having to replace the whole system. This could help you save a significant amount of money. It's also less expensive than waiting until you lose your one key.
