Saab Key Programming

Saab cars built since about 1994 feature an immobilizer mechanism based on coded keys. A new transponder is required for 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 this can be quite costly. It is recommended to always have a spare set of keys at hand.

Transponder key

The transponder is a piece of key equipped with an electronic chip. This chip sends a signal when the key is placed into the ignition. The car then checks the signal to determine whether it is the same as that of the key. If the signals match the car will then open and start. This is a great way to prevent car theft and keep your car secure from thieves.

Transponder keys could be an increasingly popular feature for cars, but they're not as secure as traditional keys made of metal. While the metal component of a traditional key may be cut and copied the transponder is protected by an electronic chip. This chip has a unique code programmed into the car's computer to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. The car can only recognize the key fob if it has an unmodified chip and programmed to match. The car won't start in the event that the key has not been programmed to match.

It is vital to have an extra Saab key. This is especially important if you reside in a rural location that has numerous car thieves. You can get a brand new key for your saab replacement key programming by going to the dealership without paying their expensive prices. In the majority of cases, you can have an original key made on the spot at a fraction of the cost you'd pay at a dealer.

Wired key

saab 9 3 key replacement cars are usually provided with two keys. If you only have one, it is an ideal idea to purchase an extra key fob as quickly as you can since if you lose it the car will require an entirely new CIM unit, and the locking cylinders need to be replaced. This can be costly especially if you're purchasing a used car.

The next step is to wire the row and column wires to the microcontroller. This is the toughest component of the project and it will require lots of soldering. There's no standard way to do it, but you should plan how to route and solder each column and row. There are 22 microcontroller pins and wires to connect for this keyboard. It has 5 rows and 17 columns.

Once the rows and columns are soldered, it's the time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins from current, thus preventing them from getting shorted. A diode permits current to only flow in one direction. It is equipped with a visible indicator of a black line that indicates which direction current will flow.

Sanabria says that some of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 can assist shoppers or DIY customers to program replacement saab car keys keys and restore immobilizer information. The tools connect to OBD ports and help the customer through each step, making the process easier than replacing the vehicle's computer.

Jump-starting the battery

A lot of people keep an assortment of tools in their trunks to jump-start a car in an emergency, however it might not be a good idea for newer cars.

Attach the red clip on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clean unpainted metal surface underneath the hood of your disabled car. The engine block is a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks, which could ignite the gasoline in the engine compartment.

Once the cables are connected, start the car and allow it to run for around five minutes. Then disconnect them in reverse. Be aware that the battery in your Saab 9-3 is recharged when you drive, so it will take a while for the battery to go back to normal. You should invest in a second key fob, as soon as you can. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement Case

Many Saab owners only have one key for their vehicle and if they lose it, key, it will cost them. It's expensive to purchase keys and will require replacing the CIM or TWICE in the case of older models. In the event of theft or any other calamity it is recommended to have a spare key. Don't purchase a used key even when it's "new." Keys that are claimed-new from aftermarket sellers will not work and are likely to fail at the crucial moment.

The dealer will charge you top dollar for only one working key. We can reset and reprogram the computer's EEEPROM in order to make it ready to accept a replacement key without the need to replace the entire system. This can help you save a significant amount of money. It's also much less expensive than waiting until you lose your only key.
