Five Killer Quora Answers On Saab Ignition Key Replacement

saab car key replacement Key Programming

saab 9-3 key programming cars made since 1994 have an immobilizer feature that is based on codes for keys. A new transponder is required in order to enable the inclusion of an additional key, as well as special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.

The issue is that this can be extremely expensive. This is why you should always have a spare key on hand.

Transponder key

The transponder is a piece of key that has an electronic chip. This chip sends a signal when the key is inserted into the ignition. The car will check to see whether the signal matches with the one on the key. If the signals match the car will then unlock and begin. This is a great way to stop car theft and keep your car secure from thieves.

Transponder keys are an extremely popular accessory for cars, but they're not as secure as traditional metal keys. While the metal portion of a traditional key can be cut and copied but a transponder key is protected by an electronic chip. The chip contains a unique code which is programmed into the car's computer in order to identify it.

When a Saab Ignition Key key fob is used, the car recognizes it and allows it to turn on. However, it can only do this if your key fob has an unmodified chip that has been programmed to match it. Otherwise, the car will reject the key and not start.

The next step is to connect the wires of columns and row to your microcontroller. This is the most challenging part of the project and will require a great deal of soldering. There's no standard way to do it, but you should plan how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the rows and column are soldered together It is now time to connect the key switches. To do this, put a diode over each key switch pin and then solder it. This will shield the pins from current, and prevent them from being shorted. A diode lets current only flow in only one direction. It has a visual indicator with a black band that indicates which direction current will flow.

Sanabria states that a number of the tools offered in auto parts stores, including 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.

Jumpstarting the battery

The majority of people have a set in their trunks to jump-start their vehicle in the event of an emergency, however it might not be the best idea for newer cars.

In the event of theft, or any other disaster it is best to have an extra key. Even if the key is "new", it will not function.

The dealer will charge you the highest dollar for only one working key. However, we can reset and re-program the computer's EEPROM to accept the new key, without replacing the whole system. This could save you a lot of money. It's much cheaper rather than wait until you loose the only key.
