saab key programming cars manufactured since 1994 feature an immobilizer mechanism that is based on codes for keys. A new transponder is required for the addition of a second key, and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The problem is that this can be very expensive. This is the reason why you should always keep a spare key in your possession.

Transponder key

The transponder key is a key with an electronic chip that sends a signal to car when it is put into the ignition. The car is able to check whether the signal matches with the one on the key. If the signals are the same, the car will unlock itself and start. This is a great method to deter car theft and keep your car secure from thieves.

Transponder keys are an increasingly popular feature in vehicles, but you should be aware they aren't as secure as classic metal keys. The metal component of the traditional keys can be easily copied and cut, but transponders are protected by an electronic chip that guards it. The chip is a unique code that's programmed into a car's computer in order to identify it.

The car will recognize the saab keys keyfob and permit it to turn on. However, it can only do this if the key fob has an unmodified chip that has been programmed to match the original. If not, the car will refuse to accept the key and will not start.

It is vital to have an extra Saab key. This is especially important if you live in a rural area where there are a lot of car burglars. The good thing is that you can find a replacement key to your saab key replacement without having to go to an auto dealer and pay the expensive prices that they demand. You can get a replacement key created on the spot for less than half of the price you'd pay at a dealership.

Key for Wired

Saab cars are typically delivered with two keys. If you only have one, it is an ideal idea to purchase an additional key fob as soon as possible since if you lose it, your car will require an entirely new CIM unit and the locking cylinders will need to be replaced. This can be expensive particularly for used cars.

The next step is to wire the wires of the column and row to the microcontroller. This is the most tedious part of the project and it will require a lot of soldering. There's no standard way to do it, but you must consider how you will route and connect each column and row. There are 22 microcontroller pins and wires to connect to this keyboard. It has 5 rows and 17 columns.

Once the rows and columns are soldered, it's time to connect them to key switches. To do this, place an inverter over each pin on the key switch and then solder it. This will protect the pins from current, thus preventing them from being cut off. A diode allows the current to flow in a single direction, and it also has a the black band as a visual indicator that indicates the direction current will flow.

Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY customers in certain cases replace keys in the program and restore lost immobilizer information, Sanabria says. The tools connect to the OBD port and guide the customer through the procedure, making it much easier than replacing the computer in the vehicle.

Jump starting the battery

Most people keep a set of jumper cables in their trunks in case of emergency, but jumping a battery in newer vehicles may not be the best idea. These vehicles are equipped with numerous digital and computers that communicate with each other. A voltage surge when the battery is connected to another could cause damage to the components making your car inoperable.

Start the vehicle you are using and allow it to run for around two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end to a clean unpainted metal surface under the hood of the damaged car. The engine block is an excellent choice. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks that could ignite the gasoline that is in the engine compartment.

After the cables have been connected, you can start the car and let it run for approximately five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 is recharged as you drive. It will take a while for it to drop back down. You should invest in another key fob when you can. Replacing the only one that works requires the installation and programming of a brand new computer chip.

Replacement Case

saab key code owners often only have one car key, and if that is lost, they'll be charged. It's costly to add the key and also requires replacing the CIM or TWICE in the case of older models. In the event of theft or other catastrophe it is recommended to have an extra key. However, don't purchase a secondhand key, even if it's "new." Keys that are claimed-new from aftermarket sellers will not perform and are almost certain to fail at the crucial moment.

The dealer will charge the highest dollars if you only have one working key. However, we can reset and re-program the computer's EEPROM in order to prepare it to accept an alternative key without replacing the whole system. This can save you a significant amount of money. It's less expensive rather than wait until you lose your only key.
