Saab Key Programming

Saab cars manufactured since 1994 utilize an immobilizer system that is based on key codes. To add an additional key, you need a new transponder, as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

The issue is that this can be very costly. It is recommended to always have an extra set of keys on hand.

Transponder key

The transponder key comes equipped with an electronic chip. It transmits a signal to the car when it is inserted into ignition. The car then checks to see whether the signal matches the one on the key. If the signals are identical, the car will unlock itself and begin. This is a great way to safeguard your car from theft.

Transponder keys are a common feature in automobiles, but you must be aware that they're not as secure as classic keys made of metal. While the metal parts of a traditional key may be cut and copied however, a transponder is secured by an electronic chip. The chip contains a unique code that is programmed into a car's computer order 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. In the absence of that, the car will reject the key and refuse to start.

It's crucial to ensure that you have a spare key for your Saab. This is particularly important when you live in a rural area with numerous car thieves. You can get a brand new key for your Saab by going to the dealership without paying their expensive costs. In most cases, you can have a new key made on-the-spot for less than half the price of what you would pay at the dealer.

Wired key

saab key programming near me cars are typically delivered with two keys. If you only have one, it is best to acquire 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 costly, especially for used cars.

The next step is to wire the row and column wires to the microcontroller. This is the most difficult part of the project, and it will require lots of soldering. There isn't a standard method to do it, but you need to think about how to connect and solder each column and row. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.

Once the rows and columns are soldered, it's the 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 shorted. A diode lets current only flow in one direction. It is equipped with a visible indicator with a black band that indicates which direction current will flow.

Sanabria says that a few of the tools available in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 are able to assist customers who are shopping or DIY customers to program replacement keys and restore immobilizer information. The tools plug into OBD ports and guide the user through each step, making the process easier than replacing the car's computer.

Jump-starting the battery

A majority of people keep an item in their trunk to jump-start their vehicle in the event of an emergency, but this might not be a good idea for vehicles that are newer. These vehicles are equipped with numerous digital and computers that communicate with one another. A surge of voltage when a battery is connected to another battery could damage the components making your car unusable.

Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface beneath the damaged car's hood. 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 trigger sparks that could ignite the gasoline in the engine compartment.

After the cables have been connected, you can begin the car and let it run for about five minutes. Then disconnect the cables in reverse. The battery in your Saab 9-3 will be recharged as you drive. It takes a while for it to fall back. You should invest in a second key fob, as soon as possible. Replacing the one that works requires the installation and programming of a brand new computer chip.

Replacement case

Many saab spare key owners only have one key for their car 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 disaster it is best to have a spare key. Even even if the key is "new", it won't work.

The dealer will charge you the most expensive dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM to be able to accept a new key without replacing the entire system. This can save you a great deal of money. It's also much less expensive than waiting until you lose your only key.
