Three Reasons Why You're Saab Ignition Key Replacement Is Broken (And How To Repair It)
Saab Key Programming
Saab cars built since about 1994 come with an immobilizer system built on coded keys. The addition of a key requires a new transponder and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
The problem is that this can be extremely expensive. This is why you should always keep a spare key in your possession.
Transponder key
The transponder key comes with an electronic chip that sends a signal to the car when it is put into the ignition. The car then checks to see whether the signal is the same as the one on the key. If the signals match it will open and start. This is a great method to deter auto theft and keep your car safe from thieves.
Transponder keys are a common feature in automobiles, however it is important to know that they are not as secure as traditional keys made of metal. The metal component of a traditional key can be easily cut and copied, whereas a transponder has an electronic chip that safeguards it. This chip contains an unique code which is programmed into a car's computer in order to identify it.
The car will recognize the Saab keyfob, and allow it to be turned on. The car can only recognize the key fob when it has a chip that is unmodified and programmed to match. The car will not start in the event that the key is not programmed to match.
It is vital to have an extra Saab key. This is particularly important especially if you reside in a rural area, where there are a lot of car burglars. The good news 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. In most instances, you can get an original key made on the spot for less than half the cost of what you'd pay at an auto dealer.
Key for Wired
Saab cars are usually delivered with two keys. If you have only one, you should purchase an additional key as soon as you can. This is because if you lose it the car will require an entirely new CIM and the locking cylinders replaced. This can be costly especially if you're purchasing a used car.
The next step is connecting the wires for columns and rows to your microcontroller. This is the most difficult part of the project and will require a great deal of soldering. It's not a common way to do it, but you must consider how you will connect and solder each column and row. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has 5 rows and 17 column.
After the rows and column are joined then it's time to connect the key switches. To do this, you need to place a diode on each pin of the key switch and solder it. This will protect the key switch pins from current and prevent them from being shorted. A diode can only allow the current to flow in a single direction, and it has an indicator in black that indicates the direction current will flow.
saab key replacement near me states that a number of the tools available in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 will assist shoppers or DIY customers to program replacement keys and restore immobilizer information. The tools connect to 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
Most people keep a few sets of jumper cables in their trunks for emergency situations however, jumping a battery for newer automobiles might not be the best idea. These vehicles are equipped with digital and computer systems that communicate with each other. A voltage spike when a battery is hooked up to another one could damage these components and render your vehicle unable to drive.
Start the vehicle you are using and allow it to run for approximately two minutes before connecting the cables to the non-working one. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged car's hood. The engine block is an excellent choice. Do not connect the black cable to the negative terminal of the dead battery as it could spark an ignition source that ignites gasoline in the engine bay.
After the cables have been connected, you need to start the vehicle and let it run about five minutes. Then, disconnect them in reverse. The battery in the Saab 9-3 will charge as you drive. It takes a while for it to drop back down. It's a good idea buy a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and a special program 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 vehicle and if they lose it, it's going to cost them. The reason for this is that it's not cheap to buy a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft or any other disaster it is best to have an extra key. Don't purchase a used key even it's "new." Keys that are claimed to be new from aftermarket sellers will not perform and are almost certain to fail at the critical moment.
The dealer will charge you top dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM to be able to accept a new key without the need to replace the entire system. This could help you save a significant amount of money. It's also much less expensive than waiting until you lose your one key.
