Saab Key Programming
Saab cars manufactured since 1994 have an immobilizer system based on coded keys. A new transponder is required to allow the addition of an extra key, and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
The problem is that it can be very expensive. It is recommended to always have a spare set of keys on hand.
Transponder key
The transponder is a piece of key with an electronic chip. The chip transmits a signal when the key is placed into the ignition. The car is able to check whether the signal is the same as the one on the key. If the signals are in sync, the car will open and start. This is a great method to protect your vehicle from theft.
Transponder keys may be a popular addition to automobiles, but they are not as secure as traditional keys made of metal. The metal component of the traditional key can be easily cut and copied, however transponders are protected by an electronic chip that guards it. The chip has a unique code that is encoded into the car's system to identify it.
The car will recognize the saab key code keyfob and permit it to be turned on. The car will only recognize the key fob if it has an unmodified chip and has been programmed to match. The car will not start if the key is not programmed to match.
It is vital to have a spare saab 93 key replacement key. This is especially true especially if you reside in a rural area, where there are a lot of car burglars. You can get a brand new key for your saab 93 replacement key by visiting the dealership, without having to pay their high cost. In most cases, you can have a new key made on-the-spot for less than half the cost you would pay at an auto dealer.
Wired key
Saab cars are usually supplied with two keys. If you have only one, it's a good idea to get an additional key fob as quickly as you can in case you lose it the car will require the replacement of a CIM unit, and the locking cylinders will need to be replaced. This can be costly, especially if you are buying a used car.
The next step is connecting the wires of columns and row to your microcontroller. This is the most tedious component of the project and will require lots of soldering. There is no standardized way to accomplish this, but it is essential to determine how you will route and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller pins and wires to connect.
After the columns and rows are soldered together, it is time to connect the key switches. To do this you must place a diode on each key switch pin and solder it. This will protect the pins that are used for key switches from current and prevent them from being shorted. The diode will only allow current to flow in one direction, and it has an indicator of black color that indicates the direction current will flow.
Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- could aid shop customers or DIY users in some cases replace keys in the program and restore lost immobilizer data Sanabria says. The tools connect to the OBD port and automatically guide the customer through the process, making it more simple than replacing the computer inside the vehicle.
Jump starting the battery
Most people keep a set of jumper cables in their trunks for emergency situations, but jumping a battery for newer vehicles might not be the most efficient option. These vehicles are equipped with numerous computers and digital devices which communicate with one another. A voltage spike when a battery is hooked up to another can fry these components and leave your car undriveable.
Start the vehicle that is working and let it run for about two minutes before connecting the cables to the non-working one. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface beneath the hood of the damaged vehicle. The engine block is a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks that could ignite the gasoline in the engine compartment.
Once the cables are connected, turn on the disabled vehicle and let it run for about five minutes before disconnecting the cables in reverse order. Remember that the battery on your Saab 9-3 is charged during your drive, which means it may take some time to get the battery back to normal. It is recommended to purchase a second key fob, when you can. Replacing the original one that works requires the installation and programming of a brand new computer chip.
Replacement Case
saab 93 key fob owners usually only have one car key, and if that is lost, they will be charged. It's expensive to add a key and requires replacing the CIM or TWICE for older models. It is recommended to have a second key in the event of theft or other disaster and the best option is to buy an extra key as quickly as you can. Don't purchase a used key, even the case that it's "new." Keys that are claimed as new purchased from third-party sellers won't work and are likely to fail in the crucial moment.
The dealer will charge you the most expensive dollar if you have only one working key. We can reset and reprogram the EEEPROM of your computer to be able to accept a replacement key without having to replace the entire system. This can help you save money. It's also much less expensive than waiting until you lose your only key.
