Saab Key Programming

Saab cars produced from 1994 have an immobilizer that relies on keys that are coded. To add an additional key, you need a new transponder and special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

It can be costly. This is why it is important to always keep a spare key in your possession.

Transponder key

The transponder can be described as a key that has an electronic chip. The chip sends a signal when the key is inserted into the ignition. The car is able to check if the signal matches the one on the key. If the signals match, the car will open and start. This is a great way to prevent auto theft and keep your car safe from thieves.

Transponder keys are a popular feature in automobiles, however it is important to know that they aren't as secure as classic metal keys. While the metal part of a traditional key could be cut and copied the transponder is protected by an electronic chip. The chip contains a unique code that's programmed into a car's computers in order to identify it.

The car will recognize the Saab keyfob and allow it to be turned on. The car can only recognize the key fob if it has a chip that is unmodified and has been programmed to match. The car will not start in the event that the key has not been programmed to match.

It's important to make sure that you have a spare key for your Saab. This is especially important if you reside in a rural location that has numerous car thieves. The good news is that it's possible to get a replacement key for your Saab without needing to visit a dealer and pay the high costs they ask. In most instances, you can get an original key made on the spot at a fraction of the cost you would pay at the dealer.

Key for Wired

Saab cars are usually supplied with two keys. If you have only one, it is recommended to purchase an additional key fob as soon as possible in case you lose it, your car will require a new CIM unit, and the locking cylinders will need to be 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 challenging part of the project and will require a great amount of soldering. It's not a common way to go about it, but you must think about how to connect and solder each column and row. There are 22 microcontroller wires and pins to connect to this keyboard. It includes 5 rows and 17 column.

After the rows and column are joined It is now time to connect the key switches. To do this, you need to place a diode on each pin of the key switch and solder it. This will protect the pins from current, thus preventing them from getting shorted. A diode allows current to flow in one direction, and it also has a an indicator in black that indicates which way the current will flow.

Some of the tools you can find at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY customers in certain cases program replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into OBD ports and guide the user through each step which makes the process much easier than replacing the vehicle's computer.

Jump-starting the battery

Most people keep a set in their trunk to jump-start a vehicle in an emergency, however it might not be the best idea for cars with more modern technology. These cars are equipped with a variety of digital and computer systems that communicate with one another. A surge in voltage when a battery is hooked up to another battery could fry these components and leave your car unable to drive.

Start the vehicle you are using and let it run for about two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the vehicle's hood. An engine block is an ideal choice. Do not connect the black cable to the negative terminal on the dead battery because it could ignite a spark that ignites the gasoline in the engine bay.

Once the cables are connected the vehicle you are not using and let it run for about five minutes before you disconnect the cables in reverse order. The battery in your Saab 9-3 is recharged as you drive. It may take a while it to return to its original state. It is recommended to purchase another key fob as soon as possible. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement case

Many saab car keys owners only have one key for their car and if they lose it, the cost will be. It's expensive to add an additional key and it requires replacing the CIM or TWICE in the case of older models. In the event of theft or any other catastrophe it is advisable to have an extra key. However, don't purchase a secondhand key even it's "new." Keys that are claimed-new from a second-hand store will not work and are likely to fail in the crucial moment.

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 top dollar to replace the computer in your car to make a new replacement. We can reset and reprogram the computer's EEEPROM for key it to accept a new key without the need to replace the entire system. That can save you lots of money. It's also much less expensive than waiting until you lose your one key.
