Saab Key Programming
Saab cars built since about 1994 have an immobilizer system that is based on codes for keys. A new transponder is required for the inclusion of an additional key, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
The problem is that it can be extremely expensive. It is always advisable to keep an extra set of keys available.
Transponder key
The transponder key comes equipped with an electronic chip. It sends a signal to the car when it is placed in the ignition. The car will then check the signal to determine whether it matches the one on the key. If the signals are identical the car will then unlock itself and begin. This is a great way to prevent auto theft and keep your car safe from thieves.
Transponder keys are a common feature in automobiles, however it is important to know that they are not as secure as classic metal keys. While the metal part of a traditional key can be cut and copied the transponder is protected by an electronic chip. This chip has an unique code that is embedded into the car's computer to identify it.
The car will recognize the
saab 9-3 key fob programming keyfob and permit it to turn on. The car will only recognize the key fob if it is equipped with 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 particularly true especially if you live in a rural area that is home to numerous car thieves. The good news is that you can find a replacement key to your Saab without needing to visit a dealer and pay the expensive prices that they demand. In the majority of instances, you can get a new key created on-the-spot for less than half the cost of what you'd pay at the dealer.
Key for Wired
Saab Ignition key replacement cars are usually provided with two keys. If you only have one, it is recommended to get an extra key as soon as you can. This is because if the key is lost, the car will need an entirely new CIM and the locking cylinders replaced. This could be expensive especially if you're purchasing a used vehicle.
The next step is connecting the wires of columns and row to your microcontroller. This is the most laborious part of the project and it will require lots of soldering. There is no standard method to accomplish this, however it is essential to determine how you will route and solder the columns and rows. 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 to each key switch pin. This will shield the pins of the key switch from current and prevent them from being shorted. A diode permits current to only flow in one direction. It has a visual indicator with a black band that indicates which direction current will flow.
Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- may help customers in the shop, or even DIY users in some cases program replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into OBD ports and help the customer through each step which makes the process much easier than replacing the vehicle's computer.
Jump starting the battery
A lot of people keep a set of jumper cables in their trunks to use in an emergency, but jumping a battery on newer automobiles might not be the best choice. They have numerous digital and computer systems that communicate with each other. A voltage surge when batteries are connected to another can fry the components making your car unusable.
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 on the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end to a clean and unpainted metal surface beneath the hood of the damaged car. The engine block is an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could result in a spark, which would ignite the gasoline in the engine compartment.
Once the cables are connected the vehicle you are not using and let it run for about five minutes before disconnecting them in reverse order. The battery in the Saab 9-3 will charge while you drive. It will take some time for it to recharge again. You should invest in a second key fob, as soon as possible. Replacing the only one that works requires the installation and programming of a new computer chip.
Replacement case
Saab owners often only have one car key, and if that is lost, they'll be charged. It's expensive to purchase the key and
saab ignition key replacement also requires replacing the CIM or TWICE for older models. It's best to have a second key in the event of theft or any other catastrophe and the most effective way is to purchase an additional key as soon as you can. Don't purchase a used key even if it's "new." Keys that are claimed-new purchased from third-party sellers won't be effective and
saab ignition key replacement are almost guaranteed to fail at the critical moment.
The dealer will charge you the highest dollar for only one working key. We can reset and reprogram the computer's EEEPROM to get it ready to accept a new key without the need to replace the entire system. This can save you lots of money. It's less expensive instead of waiting until you lose the only key.
