Saab Key Programming
Saab cars made from 1994 have an immobilizer that relies on key codes. A new transponder is required for the addition of an extra key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
This can be expensive. This is why you should always have a spare key at hand.
Transponder key
The transponder can be described as a key that has an electronic chip. This chip sends out a signal when the key is placed into the ignition. The car then checks the signal to determine whether it is the same as the one in the key. If the signals are in sync then the car will be able to open and start. This is a great way to protect your car from theft.
Transponder keys are an increasingly popular feature for automobiles, but they are not as secure as traditional keys made of metal. While the metal part of a traditional key can be cut and copied the transponder is protected by an electronic chip. This chip contains an unique code which is programmed into a car's computers in order to identify it.
The car will recognize the Saab keyfob and allow it to be turned on. However, it can only do this if the key fob is unmodified and has a chip that has been programmed to match it. The car won't start if the key is not programmed to match.
It is vital to have an extra Saab key. This is particularly important when you live in a rural area where there are a lot of car thieves. You can get a new key for your Saab by visiting the dealership and not paying their expensive prices. You can get a replacement key created on the spot for less than half of what you would pay at an auto dealer.
Key for Wired
Saab cars are usually supplied with two keys. If you own only one, you should get an additional 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 could be expensive especially if buying a used car.
The next step is to connect the row and columns wires to your microcontroller. This is the most challenging part of the project and will require a great amount of soldering. There's no standard way to go about it, but you should think about how to connect and solder each column and row. There are 22 microcontroller wires and pins to connect for this keyboard. It has five rows and 17 columns.
After the columns and rows are soldered together after which it is time to connect the key switches. To do this, place a diode over each pin on the key switch and then solder it. This will shield the pins from current and prevent them from being cut off. A diode allows current to only flow in one direction. It has a visual indicator with a black band that shows the direction in which the current will flow.
Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- could help customers in the shop, or even DIY customers in certain cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools plug into the OBD port and automatically guide the customer through the process, making it more simple than replacing the computer in the vehicle.
Jump-starting the battery
Most people keep a set in their trunks to jump start a vehicle in an emergency, however it might not be a good idea for cars with more modern technology. These vehicles are equipped with many electronic devices and computers that communicate with each other. A voltage surge when the battery is connected another battery could damage the components and render your vehicle unusable.
Start the working vehicle and let it run for about two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood--the engine block is an ideal choice. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks, which could ignite the gasoline inside the engine compartment.
Once the cables are connected, you can start the vehicle that has been disabled and allow it to run for around five minutes before you disconnect the cables in reverse order. The battery in your Saab 9-3 will recharge as you drive. It may take a while it to recharge again. It's a good idea buy a spare key fob as soon as you can, because replacing the sole working 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.
saab key fob programming thekeylab.co.uk have one car key, and if that is lost, they will be charged. The reason is that it's not inexpensive to replace a key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It is best to have a backup key in case of theft or other disaster the best solution is to purchase an additional key as quickly as you can. Even if the key is "new", it won't work.
The dealer will charge you top dollar if you only have one working key. We can reset and reprogram the EEEPROM of your computer to get it ready to accept a replacement key without the need to replace the entire system. This can help you save money. It's also much less expensive than waiting until you lose the only key.
