Saab Key Programming

Saab cars built since 1994 utilize an immobilizer system that is based on a set of keys. A new transponder is required for addition of a second 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 very expensive. This is why you should always have a spare key on hand.

Transponder key

The transponder can be described as a key that has an electronic chip. The chip sends a signal when the key is put into the ignition. The car then analyzes the signal to determine whether it matches that of the key. If the signals are identical the car will then unlock itself and begin. This is a great way to avoid car theft and keep your vehicle safe from thieves.

Transponder keys may be a popular addition to automobiles, but they are not as safe as traditional keys made of metal. The metal portion of a traditional key can easily be cut and copied, however transponders have an electronic chip which protects it. The chip is equipped with a unique code that is embedded 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. However, it will only do this if the key fob is equipped with a chip that is not modified that has been programmed to match. If not, the car will reject the key and won't start.

It's crucial to ensure that you have a spare key for your Saab. This is particularly important if you live in a rural location where there are a lot of car burglars. You can get a new key for your saab key battery - Minecraftcommand writes - by going to the dealership, without having to pay their expensive cost.

Key for Wired

Saab cars are usually delivered with two keys. If you only have one, it is a good idea to get an extra key fob as soon as you can as if you lose it, your car will require an entirely new CIM unit and the locking cylinders will have to be replaced. This could be expensive particularly if you are purchasing a used vehicle.

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 Saab Ignition Key Replacement will require lots of soldering. There is no standardized way to accomplish this, but it's important to plan out the route you'll take and solder the columns and rows. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has 5 rows and 17 column.

After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins from current, preventing them from being shorted. A diode allows current to only flow in one direction. It features a visual indicator that is black, that shows which way current will flow.

Some of the tools you can find at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- can assist customers at the shop or DIY customers in some cases create replacement keys and restore lost immobilizer data Sanabria says. The tools plug into OBD ports and guide the customer through each step, making the process easier than replacing the car's computer.

Jumpstarting the battery

Most people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery on newer cars might not be the best option. These cars are equipped with a variety of digital and computer systems that communicate with each other. A surge in voltage while a battery is hooked up to another can fry these components and leave your vehicle undriveable.

Start the vehicle that is working and allow it to run for approximately two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged vehicle's hood. An 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 gasoline in the engine compartment.

Once the cables are connected the vehicle you are not using and let it run for about five minutes before you disconnect them in reverse order. Remember that the battery on your Saab 9-3 is charged during your drive, which means it may take some time for the battery to go back to normal. It is recommended to purchase a second key fob, when you can. Replacing the one that works requires the installation and programming of a new computer chip.

Replacement case

saab keys replacement owners usually have only one car key, and if it is lost, they'll be charged. It's expensive to buy a key and 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. Even if the key is "new", it will not function.

The dealer will charge you the highest dollar if you only have one working key. We can reset and reprogram the EEEPROM of your computer for it to accept a replacement key without having to replace the entire system. This can save you a great deal of money. It's much cheaper rather than wait until you lose the only key.
