Saab Key Programming
Saab cars manufactured since 1994 feature an immobilizer that relies on coded keys. A new transponder is required for addition of an additional key, as well as special programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.
The problem is that this could be very expensive. Always keep an extra set of keys on hand.
Transponder key
The transponder key comes with an electronic chip that sends a signal back to the car when it is inserted into the ignition. The car then checks the signal to see whether it is the same as the one on the key. If the signals match, the car will unlock and begin. This is a great method to prevent auto theft and keep your car safe from thieves.
Transponder keys could be an increasingly popular feature for automobiles, but they are not as safe as traditional keys made of metal. The metal component of the traditional key can be easily copied and cut, but a transponder has an electronic chip which protects it. This chip contains an 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 turn on. However, it is only able to do so if the key fob has a non-modified chip that has been programmed to match it. If not, the car will refuse to accept the key and will not start.
It is crucial to have an extra
saab 9 3 key replacement key. This is particularly true for those who live in a rural region that has many car thieves. You can purchase a new key for your
lost saab key by visiting the dealership without paying their pricey prices. In most cases, you can have an original key made on the spot for less than half the price of what you'd pay at dealerships.
Key for Wired
Saab Ignition Key Replacement cars are typically delivered with two keys. If you have only one, it is best to acquire an additional key fob as quickly as you can, because if you lose it, the car will require a new CIM unit and the locking cylinders will have to be replaced. This could be expensive particularly if you are purchasing a used car.
The next step is to connect the row and column wires to the microcontroller. This is the most difficult component of the project and it will require lots of soldering. There is no standard method to accomplish this, but it's important to plan out the way you'll route and solder the rows and columns. 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 rows and column are joined after which it is time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins on the key switch from current and keep them from being shorted. A diode allows current to flow in one direction, and has a the black band as a visual indicator that indicates which way the current will flow.
Sanabria states that some of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508, can help shoppers or DIY customers to program
replacement key for saab 93 keys and restore data from the immobilizer. The tools plug into OBD ports and help the customer through each step making the process simpler than replacing the car'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 on modern cars might not be the best option. These cars have a variety of digital and electronic devices that communicate with one another. A voltage spike when a battery is hooked up to another battery could fry these components, rendering your vehicle undriveable.
Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip on the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end to a clean, unpainted metal surface under the hood of the disabled vehicle. The engine block is a good option. Do not connect the black cable to the negative terminal of the dead battery, since this could cause a spark that ignites the gasoline in the engine bay.
Once the cables are connected, you can start the disabled vehicle and allow it to run for around five minutes before disconnecting them in reverse order. The battery in your Saab 9-3 will recharge while you drive. It will take some time for it to return to its original state. It is a good idea to buy a spare key fob as soon as you can, because replacing the one that works requires the installation of a new computer module and special programming to convince it that your missing keys aren't attempting to steal the car.
Replacement Case
Many
saab ignition key replacement owners have only one key for their car and if they lose it, the cost will be. The reason for this is that it's not inexpensive to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or any other calamity it is advisable to have a spare key. Even if the key is "new" it won't work.
The dealer will charge you the most expensive dollar if you only have one working key. However, we can reset and re-program your computer's EEPROM to accept an alternative key without replacing the whole system. This can help you save a significant amount of money. It's cheaper to do this than wait until you lose the sole key.
