Saab Key Programming

Saab Ignition Key Replacement cars produced since 1994 use an immobilizer system that is based on keys that are coded. A new transponder is required for the addition of an extra key, and special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

This can be expensive. This is the reason why you should always have a spare key available.

Transponder key

The transponder is a key with an electronic chip. This chip sends a signal when the key is inserted in the ignition. The car then checks the signal to determine whether it is the same as the one on the key. If both signals match the car will then unlock itself and begin. This is a great way to deter car theft and keep your vehicle secure from thieves.

Transponder keys are an increasingly popular feature for automobiles, but they are not as safe as traditional metal keys. 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 individual code that is encoded into the car's system to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. But, it's only able to do this if the fob has a non-modified chip that has been programmed to match. In the absence of that, the car will reject the key and won't start.

The next step is to connect the wires for columns and rows to your microcontroller. This is the most difficult part of the project and will require a large deal of soldering. There is no standardized way to accomplish this, but it is crucial to plan the routes you'll use to solder the rows and columns. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

After the rows and column are joined, it is time to connect the key switches. To do this, put 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 can only allow the flow of current to be in one direction, and it also has a a black band visual indicator that shows 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 -- could assist customers at the shop or DIY customers in certain instances program replacement keys and restore lost immobilizer data, 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 inside the vehicle.

Jump starting the battery

Most people keep a set of jumper cables in their trunks in case of emergency, but jumping a battery for newer vehicles may not be the best option. These vehicles are equipped with many computers and digital devices which communicate with each other. A voltage surge when the battery is connected another can fry the components making your car unusable.

Connect the cables to the vehicle working. Let it run for two minutes. 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 and unpainted metal surface beneath the hood of the affected car. The engine block is a good option. Don't connect the black cable to the negative terminal on the dead battery, since it could spark a spark that ignites the gasoline in the engine bay.

Once the cables are connected, turn on the disabled vehicle and let it run for approximately five minutes before you disconnect the cables in reverse order. Be aware that the battery in your saab 93 key fob replacement 9-3 is recharged during your drive, which means it can take a while for the battery to come back to normal. It's a good idea buy 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 special programming to convince the system that your lost keys aren't attempting to steal the car.

Replacement Case

Saab owners typically only have one car key, and if that is lost, they will be charged. It's expensive to purchase an additional key and it requires replacing the CIM or TWICE in the case of older models. It's recommended to have a second key in the event of theft or other disaster and the most effective way is to purchase a second key as quickly as you can. But don't buy a used key, even it's "new." Keys that are claimed as new from a second-hand store will not work and are likely to fail at the crucial moment.

The majority of locksmiths won't be able to help when you only have one working key, and the dealer will charge you top dollar to replace the computer in your vehicle to create a replacement. We can reset and reprogram the computer's EEEPROM to be able to accept a replacement key without having to replace the entire system. That can save you lots of money. It's also less expensive than waiting until you lose your sole key.
