Saab Key Programming

Saab cars produced from 1994 have an immobilizer that relies on coded keys. A new transponder is required in order how to program saab 9-3 key fob enable the inclusion of an additional key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The issue is that it can be very costly. This is the reason why you should always have a spare key available.

Transponder key

The transponder keys are keys equipped with an electronic chip. It sends a signal to the car when it is inserted into the ignition. The car will then check the signal to determine whether it matches that of the key. If the signals match the car will be able to unlock itself and begin. This is a great method to avoid auto theft and keep your vehicle secure from thieves.

Transponder keys are an increasingly popular feature in cars, but it is important to know that they are not as secure as classic metal keys. While the metal parts of a traditional key could be cut and copied but a transponder key is protected by an electronic chip. This chip has a unique code that is programmed into the car's computer to identify it.

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

It's essential to ensure that you have an extra key for your saab 93 key programming. This is particularly important especially if you live in a rural area with numerous car thieves. The good thing is that you can find a replacement key to your Saab without having to go to an auto dealership and pay the expensive prices they ask. You can get an original key made on the spot for less than half of the price you'd pay at a dealership.

Key for Wired

Saab cars usually come with two keys when new. If you only have one, it is best to acquire an additional 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 have to be replaced. This can be costly particularly if you are purchasing a used car.

The next step is connecting the wires for columns and row to your microcontroller. This is the most challenging part of the project and requires a significant deal of soldering. There's no standard way to do this, but it's important to plan out the route you'll take and solder the columns and rows. There are 22 microcontroller wires and pins that you can connect to this keyboard. It includes 5 rows and 17 column.

After the columns and rows are joined after which it is time to connect the key switches. To do this, put a diode across each key switch pin and then solder it. This will shield the pins of the key switch from current and stop them from being shorted. A diode permits current to only flow in one direction. It has a visual indicator, a black band, that indicates which direction current will flow.

Sanabria says that some of the tools available in auto parts stores, including the Autel MaxiIM IM608PRO and IM508, can help customers shopping or DIY customers to program replacement keys and restore the immobilizer's data. The tools connect to OBD ports and help the customer through each step making the process simpler than replacing the car's computer.

Jump starting the battery

A lot of people keep a set in their trunk to start a car in case of emergency, however it might not be the best idea for vehicles that are newer. These cars are equipped with a variety of digital and computers that communicate with each other. A surge in voltage while a battery is hooked up to another can fry the components and render your vehicle undriveable.

Start the vehicle that is working and allow it to run for around two minutes before you connect the cables to the one that is disabled. Attach the red clip on the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end to a clear, unpainted metal surface underneath the hood of your disabled 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 trigger sparks that could ignite gasoline in the engine compartment.

Once the cables are connected, turn on the vehicle that is disabled and allow it to run for around five minutes before disconnecting the cables in reverse order. The battery in your Saab Ignition Key Replacement 9-3 is recharged while you drive. It may take a while it to recharge again. You should purchase a second key fob, as soon as you can. Replacing the original one that works requires the installation and programming of a brand new computer chip.

Replacement case

Many saab ignition key owners only have one key for their car and if they lose it, it's going to cost them. It's expensive to purchase a key and requires replacing the CIM or TWICE for older models. In the event of theft or any other catastrophe it is best to have an extra key. Even if the key is "new" it won't work.

The dealer will charge you top dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM to be able to accept a replacement key without replacing the entire system. That can save you a significant amount of money. It's also much less expensive than waiting until you lose the only key.
