Saab Key Programming

Saab cars produced since 1994 feature an immobilizer system that relies on key codes. Adding an extra key requires an entirely new transponder and programming. This is usually done at the dealer using a special Tech2 diagnostic tool.

The issue is that this could be very expensive. You should always keep an extra set of keys on hand.

Transponder key

The transponder key is a key with an electronic chip that sends a signal back to the car when it is inserted into ignition. The car will then check the signal to see whether it matches the one in the key. If the signals match the car will then unlock and begin. This is a great way to deter car theft and keep your vehicle safe from thieves.

Transponder keys could be an increasingly popular feature for automobiles, but they are not as secure as traditional metal keys. The metal component of the traditional key is easily cut and copied, whereas transponders have an electronic chip that guards it. The chip has an individual code that is encoded into the car’s system to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. The car will only recognize the key fob when it has a chip that is unmodified and programmed to match. If not, the car will refuse to accept the key and will not start.

It is vital to have a spare saab key (here are the findings). This is particularly true if you reside in a rural location that has numerous car thieves. You can purchase a new key for your Saab by visiting the dealership and not paying their pricey prices. In the majority of instances, you can get a brand new key made right on the spot for less than half the cost you’d pay at an auto dealer.

Key for Wired

Saab cars are typically delivered with two keys. If you only have one, it is an ideal idea to purchase an extra key fob as soon as is possible as if you lose it, the car will require an entirely 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 row and column wires to the microcontroller. This is the most tedious part of the project and will require a lot of soldering. There is no standard method to accomplish this, but it is essential to determine the way you’ll route and solder the rows and columns. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered, it’s time to connect them to key switches. Solder a diode on each key switch pin. This will shield the pins from current, thus preventing them from being shortened. A diode allows the current to flow in a single direction, and it has a black band visual indicator that shows the direction in which current will flow.

Sanabria says that a few of the tools available in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508 are able to assist shoppers or DIY customers to program replacement saab car keys keys and restore immobilizer data. The tools plug into OBD ports and help the customer through each step and make the process more straightforward than replacing the car’s computer.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunk in case of emergency however, jumping a battery on newer vehicles might not be the best choice. These vehicles are equipped with numerous electronic devices and computers that communicate with one another. A voltage surge while the battery is connected to another one could damage these components and render your car undriveable.

Start the vehicle that is working 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 is good. (It will read “POS” or “+”.) Attach the other end to a clean and unpainted metal surface under the hood of the damaged vehicle. 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 trigger a spark, which would ignite the gasoline that is in the engine compartment.

Once the cables are connected, you can start the vehicle you are not using and let it run for approximately five minutes before you disconnect the cables in reverse order. The battery in your saab 9-3 key replacement 9-3 will be recharged as you drive. It may take a while it to drop back down. It is a good idea to purchase a spare fob as soon as you can, because replacing the only working one requires the installation of a new computer module and a special program to convince it that your missing keys are not trying to steal the car.

Replacement Case

saab key battery owners often only have one car key, and if it is lost, they will be charged. The reason for this is that it’s not inexpensive to replace a key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. 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 if it’s “new.” Claimed-new keys purchased from third-party sellers won’t work and are almost guaranteed to fail at the critical moment.

Most locksmiths can’t help you with a single working key and the dealer will charge you for the cost of replacing the computer in your vehicle for a replacement. However, we can reset and re-program your computer’s EEPROM to accept the new key without having to replace the whole system. That can save you lots of money. It’s cheaper to do this rather than wait until you loose the only key.
