20 Great Tweets Of All Time About Saab Ignition Key Replacement
Saab Key Programming
Saab cars made since 1994 use an immobilizer that relies on key codes. In order to add a second key, it requires a new transponder, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
It can be costly. This is why it is important to always keep a spare key in your possession.
Transponder key
The transponder is a key equipped with an electronic chip. The chip sends a signal when the key is placed into the ignition. The car then checks to see whether the signal matches with the one on the key. If both signals match the car will then unlock itself and start. This is a great way to protect your car from theft.
Transponder keys can be an increasingly popular feature for cars, but they're not as safe as traditional keys made of metal. The metal component of the traditional key can easily be cut and copied, however the transponder is protected by an electronic chip which protects it. The chip is equipped with an individual code that is encoded into the car's system to identify it.
The car will recognize the Saab keyfob and allow it to be turned on. However, it will only do this if the key fob has an unmodified chip that has been programmed to match it. The car won't start if the key is not programmed to match.
It is vital to have a spare Saab key. This is especially true especially if you reside in a rural region where there are many car thieves. The good news is that you can find a replacement key to your Saab without having to go to a dealer and pay the high costs that they ask. In the majority of cases, you can have an original key made on the spot at a fraction of the price of what you'd pay at a dealer.
Key for Wired
Saab cars typically come with two keys when new. If you own only one, you should get an additional key as soon as you can. This is because if the key is lost, the car will need a new CIM and the locking cylinders replaced. This can be costly, especially for used cars.
The next step is connecting the wires for columns and row to your microcontroller. This is the most challenging part of the project and requires a significant deal of soldering. There isn't a standard method to do it, however, you should plan how to connect and solder each column and row. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect.
After the columns and rows are soldered, it's the time to connect them to key switches. To do this you must place a diode across each key switch pin and then solder it. This will protect the pins from current, and prevent them from being shortened. A diode only allows the current to flow in a single direction, and it has the black band as a visual indicator that indicates which way the current will flow.
Sanabria says that a few of the tools available in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 will assist customers shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools connect to OBD ports and guide the user through each step, making the process easier than replacing the vehicle's computer.
Jump starting the battery
The majority of people have a set of jumper cables in their trunks for emergency situations however, jumping a battery for newer cars might not be the best idea. These cars have a variety of electronic devices and computers that communicate with one another. A voltage spike when the battery is connected to another one could damage these components and render your car undriveable.
Start the working vehicle and allow it to run for around two minutes before you connect the cables to the battery that is not working. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood--the engine block is a good option. Do not connect the black cable to the negative terminal on the dead battery, since this could cause an ignition spark that ignites the gasoline in the engine bay.
Once the cables are connected, turn on the vehicle that has been disabled and let it run for approximately five minutes before disconnecting the cables in reverse order. Be aware that the battery of the Saab 9-3 will be charged during your drive, which means it could take a while for the battery to come down. It's a good idea buy a spare key fob as soon as you can, because replacing the only working one requires the installation of a new computer module and a special program to convince it that your lost keys aren't attempting to steal the car.
Replacement case
Saab owners often only have one car key, and if it is lost, they'll be charged. It's expensive to purchase a key and requires replacing the CIM or TWICE for older models. It is best to have a second key in the event of theft or any other catastrophe the best solution is to purchase a second key as quickly as you can. Even when the key is "new" it will not function.
The dealer will charge you the highest dollar if you only have one working key. However, we can reset and re-program your computer's EEPROM to prepare it to accept the new key, without replacing the whole system. This can help you save a significant amount of money. saab key programming www.g28carkeys.co.uk affordable instead of waiting until you lose your only key.
