Saab Key Programming
Saab cars built since about 1994 come with an immobilizer system made up of coded keys. A new transponder is required to allow the addition of an extra key, and special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.
It can be costly. This is why you should always have a spare key on hand.
Transponder key
The transponder keys are keys equipped with an electronic chip. It sends a signal to car when it is inserted into ignition. www.g28carkeys.co.uk examines the signal to determine whether it is the same as that of the key. If the signals are identical the car will then unlock itself and begin. This is a great method to safeguard your car from theft.
Transponder keys are a common feature in automobiles, however it is important to know that they aren't as secure as classic metal keys. While the metal portion of a conventional key can be cut and copied but a transponder key is protected by an electronic chip. This chip contains an unique code that's programmed into the car's computer in order to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. The car will only recognize the key fob if it has an unmodified chip and programmed to match. The car will not start if the key is not programmed to match.
It is important to have a spare Saab key. This is particularly important especially if you live in a rural area with many car thieves. You can purchase a new key for your Saab by visiting the dealership, without having to pay their high costs. In most instances, you can get a new key created on-the-spot at a fraction of the price of what you'd pay at dealerships.
Wired key
Saab cars are usually supplied with two keys. If you only have one, you should purchase an additional key as fast as you can. This is because if the key is lost, the car will need a new CIM and the locking cylinders replaced. This can be expensive, especially for used cars.
The next step is to connect the wires for the column and row to the microcontroller. This is the most challenging part of the project and requires a significant deal of soldering. There is no standardized way to accomplish this, but it is important to think about how you will route and solder the rows and columns. There are 22 microcontroller wires and pins to connect to this keyboard. It includes 5 rows and 17 columns.
After the columns and rows are joined then it's time to connect the key switches. To do this, you need to place a diode across each key switch pin and solder it. This will protect the pins on the key switch from current and prevent them from being shorted. The diode allows current to only flow in only one direction. It comes with a visual indicator of a black line that shows which way current will flow.
A few of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY users 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 which makes the process much easier than replacing the vehicle's computer.
Jumpstarting the battery
The majority of people have an item in their trunk to jump start a car in an emergency, but this might not be the best idea for vehicles that are newer. These cars are equipped with a variety of digital and computers that communicate with each other. A voltage surge while a battery is hooked up to another battery could fry these components and render your vehicle undriveable.
Start the vehicle you are using and let it run for about two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface beneath the hood of the affected car. The engine block is a good choice. Do not connect the black cable to the negative terminal of the dead battery, as it could ignite an ignition spark that ignites the gasoline in the engine bay.
Once the cables are connected, you should begin the car and allow it to run for around five minutes. Then disconnect the cables in reverse. The battery in your Saab 9-3 will be recharged while you drive. It will take a while for it to fall back. It's a good idea to purchase a spare key fob as soon as you can, since replacing the only working one requires the installation of a new computer module and a special program to convince the system that your lost keys aren't in the process of trying to steal the car.
Replacement Case
Many Saab owners only have one key for their car and if they lose it, key, it will cost them. The reason for this is that it's costly to replace a key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft, or other catastrophe it is advisable to have a spare key. Even when the key is "new", it won't work.
The dealer will charge the highest dollar if you have only 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. This could save you a significant amount of money. It's cheaper to do this rather than wait until you loose the only key.
