14 Misconceptions Common To Saab Ignition Key Replacement
saab 93 key fob Key Programming
Saab cars built since about 1994 feature an immobilizer mechanism that is based on codes for keys. A new transponder is required to allow the addition of an additional key, and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.
The problem is that this can be extremely expensive. This is why it is important to always have a spare key on hand.
Transponder key
The transponder is a type of key with an electronic chip. This chip sends out a signal when the key is put in the ignition. The Car key Service then examines the signal to see whether it is the same as the one in the key. If the signals match, the car will unlock itself and start. This is a great way to deter auto theft and keep your vehicle secure from thieves.
Transponder keys may be an increasingly popular feature for cars, but they're not as safe as traditional keys made of metal. While the metal component of a traditional key may be cut and copied, a transponder is protected by an electronic chip. This chip contains a unique code that is embedded 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. However, it is only able to do so if the key fob is unmodified and has a chip that has been programmed to match. Otherwise, the car will reject the key and won't start.
It is essential to have an extra Saab key. This is especially true especially if you live in a rural location that has numerous car thieves. You can get a new key for your Saab by visiting the dealership and not paying their pricey cost. You can have a replacement key made on the spot for less than half the cost you would pay at an auto dealer.
Wired key
saab key fob programming cars are usually provided with two keys. If you have only one, you should get an additional key as quickly as you can. This is because if it's lost, the car will need a new CIM and the locking cylinders replaced. This could be expensive, especially if you are purchasing a used vehicle.
The next step is to wire the row and column wires to the microcontroller. This is the most laborious aspect of the project and will require lots of soldering. There is no standard method to accomplish this, however it is crucial to plan the route you'll take and solder the rows and columns. There are 22 microcontroller wires and pins to connect for this keyboard. It includes 5 rows and 17 column.
After the rows and column are soldered together It is now time to connect the key switches. Solder a diode to each key switch pin. This will shield the key switch pins from current and keep them from being shorted. A diode can only allow current to flow in one direction, and it comes with a an indicator in black that indicates the direction in which current will flow.
Sanabria says that some of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508 are able to assist customers who are shopping or DIY users to program replacement keys and restore data from the immobilizer. The tools connect to OBD ports and guide 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 in their trunk to jump-start their car in an emergency, however it might not be the best idea for cars with more modern technology. These vehicles are equipped with many digital and computer systems that communicate with one another. A voltage spike when a battery is hooked up to another battery could fry these components and render your vehicle unable to drive.
Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface underneath the hood of the disabled car. The engine block is an excellent alternative. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks that could ignite the gasoline in the engine compartment.
Once the cables are connected, you can start the disabled vehicle and allow it to run for around five minutes before you disconnect them in reverse order. The battery in the Saab 9-3 will charge as you drive. It takes a while for it to recharge again. You should purchase a second key fob, when you can. The replacement of the one that works requires the installation and programming of a brand new computer chip.
Replacement case
Many Saab owners only have one key for their vehicle and if they lose it, the cost will be. The reason is that it's not inexpensive to add a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or any other disaster it is best to have an extra key. Even when the key is "new", it will not work.
The dealer will charge you the highest dollar for only one working key. However, we can reset and reprogram the computer's EEPROM to accept the new key, without replacing the whole system. This could save you a significant amount of money. It's much cheaper rather than wait until you lose the only key.
