14 Questions You Shouldn't Be Anxious To Ask Saab Ignition Key Replacement
Saab Key Programming
Saab cars made since 1994 feature an immobilizer system based on keys that are coded. A new transponder is required in order to enable the addition of an additional key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
This can be expensive. This is why you should always have a spare key on hand.
Transponder key
The transponder is a key with an electronic chip. This chip sends a signal when the key is put into 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 unlock itself and start. This is a great way to stop car theft and keep your car safe from thieves.
saab 9-3 key fob replacement are a favored feature in cars, but you should be aware that they aren't as secure as traditional keys made of metal. The metal portion of a traditional key can be easily cut and copied, however transponders have an electronic chip that safeguards it. The chip is equipped with an individual code that is programmed into the car's computers to identify it.
The car will recognize the Saab keyfob and allow it to be turned on. However, it can only do this if the key fob is unmodified and has a chip that has been programmed to match the original. The car won't start when the key isn't programmed to match.
It's crucial to ensure that you have an extra key for your Saab. This is particularly true if you reside in a rural area that is home to many car thieves. You can obtain a replacement key for your Saab by visiting the dealership and not paying their high prices. You can get a replacement key created on the spot for less than half the price you'd pay at an auto dealer.
Wired key
Saab cars are usually supplied with two keys. If you only have one, you should purchase an additional key as quickly as you can. This is because if you lose it and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be costly, especially if you are purchasing a used car.
The next step is to connect the wires for columns and row to your microcontroller. This is the most laborious part of the project and it will require a lot of soldering. It's not a standard way to do it, but you should determine how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.
After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will shield the pins on the key switch from current and keep them from being shorted. A diode allows current to only flow in only one direction. It features a visual indicator, a black band, that shows which way current will flow.
Sanabria states that a number of the tools that are sold in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 will assist shoppers or DIY users to program replacement keys and restore immobilizer data. The tools plug into the OBD port and guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.
Jump-starting the battery
A lot of people keep a set in their trunk to jump-start a car in an emergency, but this might not be a good idea for cars with more modern technology. These vehicles are equipped with a number of digital and computer systems that communicate with one another. A voltage surge while a battery is hooked up to another can fry these components and leave your vehicle undriveable.
Start the vehicle you are using and allow it to run for around two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface underneath the disabled car's hood. The engine block would be a good option. The black cable should not be connected to the negative terminal of the dead battery. This could trigger sparks that could ignite the gasoline that is in the engine compartment.
After the cables have been connected, begin the car and let it run about five minutes. Then, disconnect the cables in reverse. The battery in the Saab 9-3 will charge while you drive. It takes a while for it to drop back down. It's a good idea invest in a spare key fob as soon as you can, because replacing the only functioning one requires the installation of a brand new computer module and special programming to convince it that the lost keys are not trying to steal the car.
Replacement case
Many Saab owners only have 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 buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It is recommended to have a backup key in case of theft or other disaster, and the best way is to purchase a second key as quickly as you can. Even when the key is "new", it will not function.
The dealer will charge you top dollars if you only have 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 help you save money. It's more affordable instead of waiting until you lose the sole key.
