Saab Key Programming
Saab cars built since about 1994 come with an immobilizer system built on coded keys. Adding an extra key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
This can be expensive. It is always advisable to keep a spare set of keys available.
Transponder key
The transponder is a piece of key that has an electronic chip. This chip sends out a signal when the key is put in the ignition. The car is able to check whether the signal is the same as the one on the key. If the signals match, the car will open and start. This is a great way to safeguard your car from theft.
saab keys replacement www.thekeylab.co.uk are an increasingly popular feature in cars, but you should be aware that they're not as secure as classic metal keys. While the metal portion of a traditional key can be cut and copied however, a transponder is secured by an electronic chip. This chip has a 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 this if the fob has a non-modified chip that has been programmed to match. The car won't start when the key isn't programmed to match.
It is vital to have a spare Saab key. This is especially important for those who live in a rural region where there are numerous car thieves. You can obtain a replacement key for your Saab by visiting the dealership and not paying their pricey prices. In the majority of instances, you can get a new key made on-the-spot for less than half the cost you would pay at an auto dealer.
Wired key
Saab cars usually come with two keys upon purchase. If you only have one, you need to purchase an additional key as quickly as you can. This is because if the key is lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be costly especially for used vehicles.
The next step is to connect the wires of columns and row to your microcontroller. This is the most challenging part of the project and will require a large amount of soldering. There isn't a standard way to accomplish this, however it's important to plan out the route you'll take and solder the rows and columns. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.
After the columns and rows are soldered together It is now time to connect the key switches. To do this you must place an inverter over each pin of the key switch and solder it. This will protect the key switch pins from current and stop them from being shorted. A diode can only allow the current to flow in a single direction, and has a a black band visual indicator that indicates which way the current will flow.
Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- may assist customers at the shop or DIY users in some cases create replacement keys and restore lost immobilizer data Sanabria says. The tools connect to the OBD port and automatically guide the user through the process, making it easier than replacing the computer inside the vehicle.
Jumpstarting the battery
A majority of people keep an item in their trunks to jump-start a vehicle in the event of an emergency, but it may not be the best option for vehicles with newer technology. These vehicles are equipped with many electronic devices and computers that communicate with each other. A surge in voltage when a battery is connected to another battery could damage the components making your car unusable.
Start the vehicle that is working and allow it to run for approximately two minutes before you connect the cables to the disabled one. 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 beneath the damaged car's hood. The engine block is a good choice. The black cable should not be connected to the negative terminal of the dead battery. This could create a spark, which would ignite the gasoline that is in the engine compartment.
Once the cables are connected, turn on the vehicle that is disabled and let it run for about five minutes before disconnecting them in reverse order. Remember that the battery on your Saab 9-3 is charged when you drive, and it will take a while for the battery to come down. It's a good idea purchase 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 the system that your lost keys aren't attempting to steal the car.
Replacement case
Many Saab owners only have one key for their car and if they lose it, it's going to cost them. It's expensive to buy an additional key and it requires replacing the CIM or TWICE for older models. In the event of theft or any other disaster, it is best to have an extra key. Don't purchase a used key even if it's "new." Claimed-new keys purchased from third-party sellers won't be effective and are almost guaranteed to fail in the crucial moment.
The dealer will charge you the most expensive dollar for only one working key. We can, however, reset and re-program the computer's EEPROM in order to prepare it to accept an alternative key without replacing the whole system. This could help you save a significant amount of money. It's less expensive than waiting until you loose the only key.
