saab Key battery Key Programming
Saab cars built from 1994 have an immobilizer system that is based on keys that are coded. Adding an extra key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using a special 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 that is equipped with an electronic chip. This chip sends out a signal when the key is placed into the ignition. The car will then check the signal to see whether it is the same as that of the key. If the signals match then the car will be able to open and start. This is a great way to prevent auto theft and keep your car safe from thieves.
Transponder keys are a favored feature in automobiles, but you must be aware that they're not as secure as traditional keys made of metal. While the metal part of a traditional key may be cut and copied however, a transponder is secured by an electronic chip. This chip contains an unique code that's programmed into a car's computer in order to identify it.
When a saab spare key key fob is used, the car recognizes it and allows it to turn on. But, it's only able to do this if the key fob has an unmodified chip that has been programmed to match the original. Otherwise, the car would reject the key and won't start.
It is crucial to have an extra Saab key. This is especially important when you live in a rural region where there are a lot of car thieves. The good thing is that you can obtain a replacement key for your saab key battery replacement without having to go to an auto dealership and pay the hefty prices that they ask. In the majority of instances, you can get an original key made on the spot for less than half the cost of what you would pay at the dealer.
Key for Wired
Saab cars usually come with two keys when they're new. If you have only one, it's an ideal idea to purchase an extra key fob as soon as possible since if you lose it, your car will require the replacement of a CIM unit, and the locking cylinders will need to be replaced. This can be expensive especially for used vehicles.
The next step is to connect the wires for columns and row to your microcontroller. This is the most difficult part of the project, and will require a lot of soldering. It's not a common way to do it, but you need to determine how to connect and solder each column and row. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has 5 rows and 17 columns.
Once the rows and columns are soldered, it's the time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the key switch pins from current and prevent them from being shorted. A diode allows current to flow in one direction, and it comes with a an indicator in black that indicates the direction in which current will flow.
Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- can assist customers at the shop or DIY customers in some cases program replacement keys and restore the lost immobilizer's 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 car's computer.
Jumpstarting the battery
A lot of people keep a set of jumper cables in their trunks in case of emergency however, jumping a battery in newer cars might not be the best idea. These vehicles have many computers and digital devices that communicate with each other. A surge of voltage when the battery is connected another can fry the components, rendering your car undriveable.
Start the vehicle you are using and let it run for about two minutes before connecting the cables to the battery that is not working. Attach the red clip to the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end to a clean unpainted metal surface underneath the hood of the damaged car. The engine block is an excellent option. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks, which could ignite the gasoline inside the engine compartment.
Once the cables are connected, you should start the vehicle and let it run about five minutes. Then, disconnect them in reverse. The battery in the Saab 9-3 will charge while you drive. It will take some time for it to drop back down. It's a good idea to invest in a spare key fob as soon as you can, since replacing the only functioning one requires the installation of a brand new computer module and a special program to convince it that your lost keys aren't trying to steal the car.
Replacement Case
Saab owners usually only have one car key, and if that is lost, they'll be charged. It's costly to add an additional key and it requires replacing the CIM or TWICE in the case of older models. It's best to have a spare key in the event of theft or other disaster and the most effective way is to purchase an extra key as soon as you are able to. However, don't purchase a secondhand key, even if it's "new." Keys that are claimed-new from a second-hand store will not perform and are almost certain to fail at the critical moment.
Most locksmiths can't help you if you have only one working key, and the dealer will charge top dollar to replace the computer in your car to make a replacement. We can, however, reset and re-program your computer's EEPROM to accept an alternative key without replacing the entire system. This could save you lots of money. It's also cheaper than waiting until you lose your one key.
