Saab Key Programming

Saab cars manufactured since 1994 utilize an immobilizer system based on key codes. A new transponder is required for addition of an additional key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The issue is that this can be quite costly. This is why you should always have a spare key at hand.

Transponder key

The transponder is a type of key that has an electronic chip. This chip sends a signal when the key is put into the ignition. The car then checks to see whether the signal matches the one on the key. If the signals are in sync then the car will be able to open and start. This is a great way to avoid car theft and keep your vehicle secure from thieves.

Transponder keys can be an increasingly popular feature for cars, but they're not as secure as traditional keys made of metal. While the metal portion of a traditional key can be cut and copied but a transponder key is protected by an electronic chip. The chip contains a unique code that is programmed into a car's computers in order to identify it.

The car will recognize the saab key fob replacement keyfob and permit it to turn on. But, it's only able to do this if the fob is unmodified and has a chip that has been programmed to match. Otherwise, the car will refuse to accept the key and will not start.

This is because if you lose it and the car needs a new CIM and the locking cylinders replaced. This can be expensive, especially for used cars.

The next step is to wire the wires for the column and row to the microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. There isn't a standard method to go about it, but you should consider how you will connect and solder each column and row. There are 22 microcontroller wires and pins to connect for this keyboard. It includes 5 rows and 17 columns.

After the columns and rows are soldered, it's the time to connect them to the key switches. To do this, put a diode on each key switch pin and solder it. This will protect the pins from current, preventing them from being shorted. A diode lets current only flow in one direction. It comes with 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 aid shop customers or DIY customers in certain cases program replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into OBD ports and guide the customer through each step, making the process easier than replacing the vehicle's computer.

Jumpstarting the battery

A majority of people keep an assortment of tools in their trunks to jump-start a car in case of emergency, but it may not be a good idea for cars with more modern technology. These cars have a variety of digital and computer systems that communicate with each other. A voltage spike when batteries are connected to another can fry 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 battery that's good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface beneath the damaged car's hood--the engine block is a good option. Don't connect the black cable to the negative terminal on the dead battery, as this could cause a spark that ignites the gasoline in the engine bay.

Once the cables are connected, you can start the vehicle that is disabled and allow it to run for around five minutes before disconnecting the cables in reverse order. Remember that the battery on your saab replacement keys 9-3 is charged when you drive, so it will take a while to get the battery down. It's a good idea invest in 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 the lost keys aren't attempting to steal the car.

Replacement case

Many saab ignition key replacement (www.cheaperseeker.Com) owners only have one key for their car and if they lose that it's going to cost them. The reason is that it's expensive to purchase a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or any other calamity, it is best to have a spare key. Even it's "new", it won't work.

The dealer will charge the highest dollar if you have only one working key. We can reset and reprogram the EEEPROM of your computer to get it ready to accept a new key without replacing the entire system. This can save you a lot of money.
