Saab Key Programming
Saab cars manufactured since 1994 come with an immobilizer system built on coded keys. A new transponder is required for addition 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 this can be quite costly. This is why it is important to always have a spare key on hand.
Transponder key
The transponder is a type of key with an electronic chip. This chip sends out a signal when the key is placed in the ignition. The car then checks the signal to see whether it matches the one that is in the key. If the signals match then the car will be able to unlock and begin. This is a great method to stop car theft and keep your car safe from thieves.
Transponder keys are a favored feature in vehicles, but you must be aware that they’re not as secure as classic metal keys. While the metal portion of a conventional key can be cut and copied however, a transponder is secured by an electronic chip. The chip is a unique code that is programmed into a car’s computer in order to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. However, it is only able to do so if the key fob has an unmodified chip that has been programmed to match it. In the absence of that, the car will reject the key and won’t start.
It is vital to have an extra Saab key. This is especially important if you reside in a rural area that is home to many car thieves. You can get a brand new key for your saab fob key replacement by visiting the dealership without paying their pricey costs. In most cases, you can have a new key made on-the-spot for less than half the cost you’d pay at dealerships.
Wired key
Saab cars usually come with two keys when they are new. If you have only one, it’s best to acquire an extra key fob as quickly as you can as if you lose it the car will require the replacement of a CIM unit, and the locking cylinders need to be replaced. This can be expensive especially for cars that are used.
The next step is connecting the wires for columns and row to your microcontroller. This is the most difficult part of the project and will require a great amount of soldering. There is no standard method to do this, but 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 to connect.
After the rows and column are joined It is now time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins on the key switch from current and stop them from being shorted. A diode only allows the flow of current to be in one direction, and it comes with a a black band visual indicator that indicates which way the current will flow.
Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 — can help customers in the shop, or even DIY customers in certain instances replace keys in the program and restore the lost immobilizer’s data, Sanabria says. The tools connect to OBD ports and guide the customer through each step making the process simpler than replacing the car’s computer.
Jump-starting the battery
Most people keep a set of jumper cables in their trunk in case of emergency, but jumping a battery in newer cars might not be the best option. These vehicles are equipped with numerous digital and computers that communicate with each other. A voltage surge while the battery is connected to another battery could fry the components and render your vehicle unable to drive.
Connect the cables to the vehicle operating. Let it run for two minutes. 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 under the hood of your disabled vehicle. The engine block is a good option. Do not connect the black cable to the negative terminal of the dead battery because it could ignite an ignition spark that ignites the gasoline in the engine bay.
Once the cables are connected, you should start the vehicle and allow it to run for around five minutes. Then disconnect the cables in reverse. Be aware that the battery of the Saab 9-3 will be charged when you drive, so it could take a while for the battery to come down. It is recommended to purchase a second key fob, as soon as possible. Replacing the original one that works requires the installation and programming of a new computer chip.
Replacement Case
Saab owners usually only have one car key, and if that is lost, they will be charged. The reason is that it’s costly to add a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It is best to have a spare key in case of theft or any other catastrophe, and the best way is to purchase an additional key as early as you can. Even it’s “new”, it will not work.
Most locksmiths aren’t able to help if you have only one working key and the dealer will charge top dollar to replace the computer in your car to create a replacement saab key programmer car keys, te.legra.ph,. However, we can reset and re-program the computer’s EEPROM to accept the new key without having to replace the entire system. This can save you a great deal of money. It’s also much less expensive than waiting until you lose the only key.
