saab keys cars manufactured since 1994 have an immobilizer system based on coded keys. A new transponder is required in order how to open a saab 93 without a key enable the inclusion of an additional key, as well as special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.
It can be costly. This is why you should always have a spare key on hand.
Transponder key
The transponder is a key equipped with an electronic chip. The chip transmits a signal when the key is put in the ignition. The car then analyzes the signal to see whether it matches the one in the key. If the signals match the car will be able to unlock itself and begin. This is a great method to stop auto theft and keep your vehicle secure from thieves.
Transponder keys are a common feature in automobiles, however you must be aware that they are not as secure as traditional metal keys. The metal part of the traditional key can be easily cut or copied, while a transponder has an electronic chip that safeguards it. This chip has an unique code that is embedded into the car's computer to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it can only do so if the key fob is unmodified and has a chip that has been programmed to match. Otherwise, the car will refuse to accept the key and will not start.
It is crucial to have an extra saab 93 key fob replacement key. This is especially true especially if you reside in a rural location where there are numerous car thieves. The good thing is that you can find a new key for your Saab without having to go to an auto dealer and pay the high prices they ask. In most instances, you can get a new key created on-the-spot for less than half the price of what you would pay at an auto dealer.
Wired key
Saab cars are usually provided with two keys. If you only have one, it's an ideal idea to purchase an extra key fob as soon as you can as if 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 expensive particularly 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 amount of soldering. There is no standardized way to accomplish this, however it's important to plan out the route you'll take and solder the columns and rows. There are 22 microcontroller wires and pins to connect for this keyboard. It includes 5 rows and 17 column.
After the columns and rows are soldered, it's time to connect them to key switches. To do this, you need to place an inverter over each pin on the key switch and then solder it. This will protect the pins from current, preventing them from being cut off. A diode can only allow the current to flow in a single direction, and it also has a a black band visual indicator that shows the direction in which current will flow.
Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- can aid shop customers or DIY customers in certain cases program replacement keys and restore the lost immobilizer's data, Sanabria says. The tools connect to the OBD port and automatically guide the customer through the process, making it easier than replacing the computer inside the vehicle.
Jump starting the battery
The majority of people have the set in their trunk to jump-start their car in case of emergency, but this might not be a good idea for vehicles that are newer. These vehicles have many electronic devices and computers that communicate with one another. A surge in voltage while the battery is connected to another battery could fry these components and leave your vehicle undriveable.
Start the working vehicle and let it run for about two minutes before connecting the cables to the battery that is not working. Attach the red clip to the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface beneath the hood of your disabled vehicle. The engine block is a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks, which could ignite gasoline in the engine compartment.
Once the cables are connected, start the car and allow it to run for around five minutes. Then, disconnect the cables in reverse. The battery in the Saab 9-3 will charge as you drive. It will take a while for it to drop back down. It's a good idea purchase a spare fob as soon as you can, since replacing the only functioning one requires the installation of a brand new computer module and a special program to convince the system that your lost keys aren't in the process of trying to steal the car.
Replacement Case
Many Saab owners have only one key for their car and if they lose that it's going to cost them. The reason is that it's not cheap to replace a key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft, or other catastrophe it is recommended to have a spare key. But don't buy a used key, even the case that it's "new." Keys that are claimed to be new from sellers selling aftermarket keys won't work and are likely to fail at the critical moment.
Most locksmiths can't help you in the event that you only have one working key, and the dealer will charge for the cost of replacing the computer in your vehicle to create a replacement. However, we can reset and re-program your computer's EEPROM to accept the new key without having to replace the entire system. This could save you a great deal of money. It's less expensive instead of waiting until you loose the only key.
