Saab Key Programming
Saab cars built from 1994 have an immobilizer system based on keys that are coded. A new transponder is required in order to enable the addition of an additional key, and special programming. This is usually done at the dealer using a special Tech2 diagnostic tool.
It can be costly. This is why it is important to always have a spare key on hand.
Transponder key
The transponder can be described as a key that has an electronic chip. This chip sends a signal when the key is placed in the ignition. The car then checks the signal to see whether it is identical to the one that is in the key. If the signals are in sync the car will then unlock and begin. This is a great method to prevent car theft and keep your vehicle secure from thieves.
Transponder keys are a common feature in vehicles, but it is important to know that they're not as secure as classic keys made of metal. The metal portion of a traditional key is easily cut and copied, whereas a transponder has an electronic chip which protects it. The chip contains a unique code that is programmed into a car's computer order to identify it.
The car will recognize the Saab keyfob and permit it to turn on. However, it can only do this if the key fob has a non-modified chip that has been programmed to match the original. The car won't start in the event that the key is not programmed to match.
It's crucial to ensure that you have a spare key for your Saab. This is especially true when you live in a rural region that has many car thieves. You can obtain a replacement key for your Saab by visiting the dealership without paying high cost. In the majority of instances, you can get a brand new key made right on the spot for less than half the cost you'd pay at dealerships.
Wired key
Saab cars typically come with two keys when they are new. If you only own one, you should get an extra key as soon as you can. This is because if it's lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be costly especially if purchasing a used vehicle.
The next step is to connect the column and row wires to the microcontroller. This is the most difficult aspect of the project and will require a lot of soldering. There's no standard way to do it, but you must plan how to connect and solder each column and row. There are 22 microcontroller pins and wires to connect for this keyboard. It includes 5 rows and 17 column.
After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode to each key switch pin. This will protect the key switch pins from current and prevent them from being shorted. A diode only allows the current to flow in a single direction, and it comes with a an indicator in black that indicates the direction current will flow.
Sanabria states that some of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508 can assist shoppers or DIY customers to program replacement keys and restore the immobilizer's data. The tools plug into the OBD port and automatically guide the customer through the procedure, making it simpler than replacing the computer inside the vehicle.
Jump-starting the battery
Most people keep an assortment of tools in their trunks to jump-start their car in an emergency, but it may not be a good idea for cars with more modern technology. These vehicles have many digital and computer systems that communicate with each other. A surge in voltage while a battery is hooked up to another one could damage these components and leave your vehicle undriveable.
Start the vehicle you are using and let it run for about two minutes before connecting the cables to the non-working one. Attach the red clip to the positive terminal of the battery that's good. (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 a great option. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks that could ignite gasoline in the engine compartment.
Once the cables are connected, start the vehicle and allow it to run for around five minutes. Then disconnect how to open a saab 93 without a key G28 in reverse. The battery in your Saab 9-3 is recharged while you drive. It will take some time for it to recharge again. You should purchase another key fob when you can. Replacing the one that works requires the installation and programming of a new computer chip.
Replacement case
Saab owners usually only have one car key, and if it is lost, they'll be charged. The reason is that it's not cheap to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or other catastrophe it is best to have an extra key. However, don't purchase a secondhand key even the case that it's "new." Keys that are claimed-new from a second-hand store will not be effective and are almost guaranteed to fail at the critical moment.
Most locksmiths can't help you if you have only one working key, and the dealer will charge you for the cost of replacing the computer in your car to make a new replacement. We can, however, reset and reprogram the computer's EEPROM to prepare it to accept the new key, without replacing the whole system. This can save you a great deal of money. It's much cheaper rather than wait until you loose the only key.
