saab key programming (

Saab cars built since about 1994 have an immobilizer system that is based on codes for keys. The addition of a key requires a new transponder and special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.
The issue is that this can be very expensive. This is the reason why you should always have a spare key at hand.
Transponder key
The transponder is a type of key with an electronic chip. This chip sends out a signal when the key is inserted into the ignition. The car will then check the signal to determine whether it matches the one in the key. If both signals match the car will then unlock itself and start. This is a great method to avoid auto theft and keep your vehicle safe from thieves.
Transponder keys are an increasingly popular feature in automobiles, however you should be aware that they aren't as secure as traditional metal keys. The metal component of a traditional key is easily cut and copied, however transponders are protected by an electronic chip that protects it. The chip contains a unique code that is inserted into a car's computer in order to identify it.
The car will recognize the

It's crucial to ensure that you have a spare key for your
saab key battery replacement. This is especially true if you live in a rural area where there are a lot of car thieves. The good thing is that you can find a replacement key to your
saab key battery without needing to visit an auto dealership and pay the high prices they ask. You can have an original key made on the spot for less than half of the price you'd pay at dealerships.
Key for Wired
saab replacement key programming cars usually come with two keys upon purchase. If you own only one, you need to purchase an additional key as fast as you can. This is because if you lose it and the car needs a new CIM and the locking cylinders replaced. This could be expensive especially if buying a second-hand car.
The next step is to connect the row and column wires to the microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. There's no standard way to do it, but you need to consider how you will route and solder each column and row. There are 22 microcontroller pins and wires to connect for this keyboard. It has 5 rows and 17 column.
After the columns and rows are soldered together after which it is time to connect the key switches. To do this you must place a diode on each pin on the key switch and solder it. This will shield the pins that are used for key switches from current and prevent them from being shorted. A diode can only allow current to flow in one direction, and it comes with a an indicator of black color that indicates which way the current will flow.
Some of the tools you can find at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- could aid shop customers or DIY customers in some cases program replacement keys and restore lost immobilizer data Sanabria says. The tools plug into OBD ports and guide the customer through each step, making the process easier than replacing the vehicle's computer.
Jump-starting the battery
A lot of people keep a set of jumper cables in their trunks for emergencies however, jumping a battery in newer vehicles might not be the best option. These cars have a variety of electronic devices and computers that communicate with each other. A voltage surge while the battery is connected to another could cause damage to these components, rendering your vehicle undriveable.
Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip on the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood--the engine block is a good choice. Don't connect the black cable to the negative terminal of the dead battery because this could cause an ignition 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. Be aware that the battery in the Saab 9-3 gets recharged while you drive, so it will 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, since replacing the sole working one requires the installation of a brand new computer module and a special program to convince it that the 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 that the cost will be. The reason for this is that it's not inexpensive to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It's recommended to have a second key in the event of theft or other disaster the best solution is to purchase an additional key as early as you can. Even it's "new", it will not function.
The dealer will charge you top dollars if you only have one working key. However, we can reset and re-program the computer's EEPROM to prepare it to accept a new key without replacing the entire system. That can help you save money. It's more affordable than waiting until you lose the only key.
