Saab Key Programming Saab cars that were built prior to 1994 feature an immobilizer mechanism built on coded keys Adding an extra key requires an entirely new transponder and programming This is usually done by the dealer using the Tech2 diagnostic tool The issue is that it can be very expensive It is always advisable to keep a spare set of keys available Transponder key The transponder is a type of key that has an electronic chip This chip sends a signal when the key is placed in the ignition The car will check to see whether the signal is the same as the one on the key If the signals match then the car will be able to unlock and start This is a great way to stop auto theft and keep your car safe from thieves Transponder keys are a favored feature in automobiles, however it is important to know that they're not as secure as classic metal keys While the metal part of a conventional key can be cut and copied but a transponder key is protected by an electronic chip The chip has a unique code which is programmed into a car's computer in order to identify it When a Saab key fob is used the car recognizes it and allows it to turn on The car can only recognize the key fob when it has a chip that is unmodified and programmed to match The car will not start in the event that the key is not programmed to match It's important to make sure that you have an extra key for your Saab This is especially important especially if you live in a rural location that has many car thieves The good thing is that you can find a replacement key to your Saab without needing to visit a dealer and pay the high prices that they demand In the majority of cases, you can have a new key made on-the-spot at a fraction of the price of what you'd pay at an auto dealer Key for Wired Saab cars typically come with two keys upon purchase If you have only one, you need to purchase an additional key as soon as you can This is because if you lose it the car will require an entirely new CIM and the locking cylinders replaced This could be expensive, especially if you are buying a used car https//wwwthekeylabcouk/saab-car-keys/ is to connect the row and columns wires to your microcontroller This is the most difficult part of the project and will require a large amount of soldering There's no standard way to do 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 to this keyboard It has 5 rows and 17 column Once the rows and columns are soldered, it's time to connect them to key switches Solder a diode on each key switch pin This will shield the pins on the key switch from current and stop them from being shorted A diode can only allow the current to flow in a single direction, and has a an indicator of black color that indicates the direction current will flow A few of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- may aid shop customers or DIY customers in certain cases replace keys in the program and restore the lost immobilizer's data, Sanabria says The tools connect to OBD ports and help the customer through each step making the process simpler than replacing the vehicle's computer Jumpstarting the battery A lot of people keep a set of jumper cables in their trunk to use in an emergency, but jumping a battery on newer vehicles might not be the most efficient option These cars are equipped with a variety of computers and digital devices which communicate with one another A voltage surge while a battery is hooked up to another can fry these components, rendering your car unable to drive Start the vehicle that is working and let it run for about two minutes before you connect the cables to the non-working one Attach the red clip to the positive terminal on the battery that is good it will have "POS" or "+" on it Attach the other end to a clean unpainted metal surface under the hood of the damaged car The engine block is an excellent alternative Do not connect the black cable to the negative terminal on the dead battery, as this could cause an ignition source that ignites gasoline in the engine bay Once the cables are connected, you can start the car and let it run about five minutes Then disconnect the cables in reverse The battery in your Saab 9-3 is recharged as you drive It will take a while for it to drop back down It is a good idea to purchase a spare fob as soon as you can, since replacing the one that works requires the installation of a new computer module and a special program to convince it that your lost keys aren't trying to steal the car Replacement case Many Saab owners only have one key for their car and if they lose it, the cost will be The reason for this is that it's costly to purchase a new key, and it requires replacing the CIM Column Integration Module or TWICE on older models, in addition to programming It is recommended to have a second key in case of theft or any other catastrophe and the most effective way is to purchase an additional key as quickly as you can Don't buy a secondhand key even if it's "new" Keys that are claimed as new purchased from third-party sellers won't perform and are almost certain to fail at the critical moment The dealer will charge you the most expensive dollars if you only have one working key We can reset and reprogram the EEEPROM of your computer to get it ready to accept a new key without replacing the entire system That can save you lots of money It's cheaper to do this rather than wait until you lose the sole key
