Saab Key Programming

Saab cars manufactured since 1994 come with an immobilizer system based on coded keys. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

The problem is that this can be quite costly. It is always advisable to keep an extra set of keys at hand.

Transponder key

The transponder key comes with an electronic chip that sends a signal to the car when it is placed in the ignition. The car will then check the signal to determine if it matches the one in the key. If the signals are the same the car will then unlock itself and begin. This is a great method to safeguard 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 conventional key can be cut and copied however, a transponder is secured by an electronic chip. This chip contains an unique code that is inserted into a car's computer in order to identify it.

When a saab 9-3 key fob programming key fob is used, the car recognizes it and allows it to turn on. However, it will only do this if the key fob has a non-modified chip that has been programmed to match the original. If not, the car will reject the key and not start.

It's essential to ensure that you have an extra key for your saab replacement key. This is particularly true for those who live in a rural area that is home to many car thieves. The good news is that you can obtain a replacement key for saab 93 key for your Saab without needing to visit a dealer and pay the high costs that they charge. You can have an original key made on the spot for less than half what you would spend at dealerships.

Wired key

Saab cars usually come with two keys when they're new. If you only have one, it's recommended to purchase an extra key fob as soon as possible, because if you lose it, the car will require the replacement of a CIM unit and the locking cylinders will have to be replaced. This can be costly especially for used vehicles.

The next step is connecting the row and columns wires to your microcontroller. This is the most tedious aspect of the project and it will require lots of soldering. There is no standardized way to accomplish this, but it's important to plan out the route you'll take and solder the rows and columns. There are 22 microcontroller wires and pins to connect for this keyboard. It has five rows and 17 column.

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 pins from current and prevent them from getting shorted. A diode lets current only flow in only one direction. It has a visual indicator, a black band, that indicates which direction current will flow.

A few of the tools that are available at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- can help customers in the shop, or even DIY customers in some cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools plug into the OBD port and automatically guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.

Jump-starting the battery

The majority of people have the set in their trunks to jump-start their car in an emergency, but it may not be a good idea for cars with more modern technology. These vehicles are equipped with a number of digital and computer systems that communicate with one another. A surge in voltage while the battery is connected to another one could damage these components and render your vehicle unable to drive.

Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface underneath the hood of the affected vehicle. The engine block is an excellent alternative. The black cable should not be connected to the negative terminal of the dead battery. This could create sparks, which would ignite the gasoline inside the engine compartment.

Once the cables are connected, you can start the vehicle and let it run about five minutes. Then disconnect them in reverse. The battery in your saab 9-3 key programming 9-3 is recharged as you drive. It takes a while for it to drop back down. You should purchase an additional key fob when you can. Replacing the only one that works requires the installation and programming of a brand new computer chip.

Replacement case

saab ignition Key owners usually only have one car key, and if that is lost, they will be charged. The reason is that it's costly to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's recommended to have a backup key in the event of theft or any other catastrophe and the most effective way is to purchase an extra key as early as you can. Even it's "new", it won't work.

The majority of locksmiths won't be able to help in the event that you only have one working key, and the dealer will charge you high fees to replace the computer in your car to make a new replacement. However, we can reset and re-program your computer's EEPROM in order to prepare it to accept the new key without having to replace the whole system. That can save you a lot of money. It's also a lot cheaper than waiting until you lose your sole key.
