Saab Key Programming

Saab cars built from 1994 have an immobilizer system that is based on coded keys. A new transponder is required for addition of an additional key, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

The problem is that it can be quite costly. It is recommended to always have an extra set of keys on hand.

Transponder key

The transponder keys are keys equipped with an electronic chip. It sends a signal to the car when it is put into the ignition. The car will check to see whether the signal is the same as the one on the key. If the signals are identical the car will be able to unlock itself and begin. This is a great way to prevent car theft and keep your vehicle safe from thieves.

Transponder keys are a common feature in cars, but you must be aware that they're not as secure as classic keys made of metal. While the metal portion of a traditional key may be cut and copied, a transponder is protected by an electronic chip. The chip is equipped with an individual code that is programmed into the car's computer to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. The car will only recognize the key fob if it has an unmodified chip and has been programmed to match. In the absence of that, the car will reject the key and not start.

It is crucial to have an extra saab key fob repair key. This is particularly true if you reside in a rural area with many car thieves. The good news is that you can find a replacement key to your Saab without having to go to an auto dealership and pay the expensive prices that they ask. In the majority of cases, you can have an original key made on the spot for less than half the price of what you'd pay at an auto dealer.

Key for Wired

saab key code cars typically come with two keys when they are new. If you only own one, you should get an extra key as soon as you can. This is because if it's lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be costly particularly if you are buying a second-hand car.

The next step is to connect the wires of the column and row to the microcontroller. This is the most difficult part of the project and requires a significant amount of soldering. There's no standard way to do it, but you need to think about how to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

Once the rows and columns are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will protect the pins from current, thus preventing them from getting shorted. A diode lets current only flow in one direction. It has a visual indicator that is black, that shows which way current will flow.

Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- may aid shop customers or DIY customers in certain cases replace keys in the program and restore lost immobilizer information, Sanabria says. The tools plug into OBD ports and guide the user through each step and make the process more straightforward than replacing the car's computer.

Jumpstarting the battery

The majority of people have a set in their trunk to jump-start a car in an emergency, however it might not be the best idea for vehicles that are newer. They have numerous electronic devices and computers that communicate with each other. A voltage surge while the battery is connected to another could cause damage to the components and render your car unable to drive.

Start the vehicle you are using and allow it to run for around two minutes before connecting the cables to the one that is disabled. 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 of the black cable to a clean, unpainted metal surface underneath the vehicle's hood. An engine block is a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could cause a spark, which would ignite gasoline in the engine compartment.

Once the cables are connected, start the vehicle that has been disabled and let it run for approximately five minutes before you disconnect them in reverse order. The battery in your saab ignition key Replacement 9-3 is recharged 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, since replacing the sole working one requires the installation of a new computer module and a special program to convince it that the lost keys aren't attempting to steal the car.

Replacement Case

Many Saab owners only have one key for their car and if they lose it, they'll be charged. It's expensive to add the key and also requires replacing the CIM or TWICE in the case of older models. In the event of theft, or any other disaster, it is best to have an extra key. Even when the key is "new", it won't work.

The dealer will charge you top dollar for Saab Ignition key replacement only one working key. We can, however, reset and reprogram the computer's EEPROM to accept an alternative key without replacing the whole system. This could save you lots of money. It's much cheaper rather than wait until you loose the only key.
