Saab Key Programming Saab cars built since about 1994 come with an immobilizer system that is based on codes for keys. A new transponder is required for the 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 it can be very expensive. It is always advisable to keep a spare set of keys at hand. Transponder key The transponder is a piece of key equipped with an electronic chip. This chip sends a signal when the key is placed into the ignition. The car checks to see if the signal matches the one on the key. If the signals match it will open and start. This is a great way to deter auto theft and keep your car safe from thieves. Transponder keys can be a popular addition to cars, but they're not as secure as traditional metal keys. 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's programmed into the car's computer in order to identify it. The car will recognize the Saab keyfob and allow it to be turned on. The car will only recognize the key fob if it has an unmodified chip and programmed to match. If not, the car will reject the key and refuse to start. It is crucial to have a spare Saab key. This is especially true especially if you reside in a rural area, where there are many car thieves. The good news is that it's possible to find a new key for your Saab without needing to visit a dealer and pay the hefty prices that they charge. In most cases, you can have a brand new key made right on the spot at a fraction of the cost of what you'd pay at the dealer. Wired key Saab cars are typically delivered with two keys. If you only own one, you need to purchase an extra key as soon as you can. This is because if the key is lost and the car needs a new CIM and the locking cylinders replaced. This can be costly, especially if you are buying a used car. saab replacement key is to wire the row and column wires to the microcontroller. This is the most difficult part of the project and will require a large amount of soldering. There is no standard method to accomplish this, but it is essential to determine the routes you'll use to solder the rows and columns. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has five rows and 17 columns. After the columns and rows are soldered together after which it is time to connect the key switches. To do this, place a diode across each pin of the key switch and solder it. This will protect the key switch pins from current and also prevent them from being shorted. The diode allows current to 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 some of the tools that are sold in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 are able to assist customers who are shopping or DIY customers to program replacement keys and restore the immobilizer's data. The tools plug into OBD ports and guide the customer through each step, making the process easier than replacing the car's computer. Jump-starting the battery A lot of people keep a set of jumper cables in their trunk for emergency situations however, jumping a battery on newer vehicles might not be the best option. These vehicles are equipped with a number of digital and electronic devices that communicate with each other. A voltage surge when the battery is connected to another battery could damage the components making your car inoperable. Start the vehicle that is working and allow it to run for approximately two minutes before connecting the cables to the one that is disabled. Attach the red clip to the positive terminal of the battery that's good. (It will read POS or +.) Attach the other end of the black cable to an unpainted, clean metal surface underneath the disabled car's hood--the engine block is a good option. Do not connect the black cable to the negative terminal of the dead battery as it could spark an ignition spark that ignites the gasoline in the engine bay. Once the cables are connected the vehicle you are not using and let it run for approximately five minutes before you disconnect them in reverse order. The battery in the Saab 9-3 will charge while you drive. It takes a while for it to drop back down. It's a good idea to purchase a spare fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and a special program to convince it that the lost keys aren't attempting to steal the car. Replacement case Many Saab owners only have one key for their vehicle and if they lose it, they'll be charged. The reason for this is that it's costly to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft or other catastrophe it is advisable to have a spare key. Don't buy a secondhand key, even the case that it's new. Keys that are claimed-new from aftermarket sellers will not work and are almost guaranteed to fail in the crucial moment. Most locksmiths aren't able to help with a single working key, and the dealer will charge you high prices to replace the computer in your car to create a replacement. We can reset and reprogram the EEEPROM of your computer for it to accept a new key without replacing the entire system. This could save you lots of money. It's also less expensive than waiting until you lose your only key.
