saab spare key Key Programming

Saab cars built since 1994 use an immobilizer that relies on coded keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

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

Transponder key

The transponder key is a piece of hardware with an electronic chip that sends a signal to car when it is placed in the ignition. The car then checks to see whether the signal matches with the one on the key. If the signals are the same the car will be able to unlock itself and begin. This is a great way to avoid auto theft and keep your car safe from thieves.

Transponder keys are a popular addition to cars, but they are not as secure as traditional metal keys. The metal component of a traditional key can easily be cut and copied, however the transponder is protected by an electronic chip that guards it. The chip is equipped with an unique code that is programmed into the car's computers to identify it.

The car will recognize the saab key fob keyfob and permit it to be turned on. But, it's only able to do so if the key fob has a non-modified chip that has been programmed to match. In the absence of that, the car will reject the key and won't start.

If you only have one, it is an ideal idea to purchase an additional key fob as soon as is possible, because if you lose it, your car will require a new CIM unit, and the locking cylinders will need to be replaced. This could be expensive especially if you're purchasing a used car.

The next step is to connect the wires of the column and row to the microcontroller. This is the most laborious aspect of the project and it will require a lot of soldering. It's not a common way to go about it, but you must determine how to connect and solder each column and row. There are 22 microcontroller wires and pins that you can connect for this keyboard. It has five rows and 17 columns.

After the columns and rows are soldered, it's the time to connect them to the key switches. To do this, put a diode across each pin on the key switch and then solder it. This will shield the pins from current and prevent them from being shorted. A diode only allows current to flow in one direction, and it has the black band as a visual indicator that shows the direction in which current will flow.

Some of the tools you can find at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- can help customers in the shop, or even DIY users in some cases program replacement keys and restore lost immobilizer data Sanabria says. The tools connect to the OBD port and automatically guide the customer through the procedure, making it simpler than replacing the computer inside the vehicle.

Jump-starting the battery

A majority of people keep an assortment of tools in their trunks to start a vehicle in the event of an emergency, but it might not be a good idea for newer cars. These vehicles have many digital and computer systems that communicate with one another. A voltage surge when batteries are connected to another battery could damage the components making your car inoperable.

Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip to the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end to a clear, unpainted metal surface underneath the hood of the affected vehicle. The engine block is a good choice. Don't connect the black cable to the negative terminal of the dead battery because it could spark an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, you can begin the car and let it run for about five minutes. Then, disconnect the cables in reverse. Keep in mind that the battery on your saab 93 replacement key 9-3 is recharged when you drive, and it could take a while to get the battery back to its original level. You should consider purchasing an additional key fob when you can. The replacement of the one that works requires the installation and programming of a brand new computer chip.

Replacement Case

Many saab 9-3 key not accepted contact service (telegra.ph) owners have only one key for their car and if they lose it, the cost will be. It's costly to add keys and will require replacing the CIM or TWICE for older models.
