saab key programmer Key Programming

Saab cars manufactured since 1994 come with an immobilizer system that is based on codes for keys. A new transponder is required for the addition of a second key, and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

This can be expensive. This is why it is important to always have a spare key available.

Transponder key

The transponder keys are keys equipped with an electronic chip. It sends a signal to car when it is placed in the ignition. The car will then check the signal to see whether it is identical to that of the key. If the signals are in sync then the car will be able to open and start. This is a great method to safeguard your car from theft.

Transponder keys may be a popular addition to automobiles, but they are not as secure as traditional keys made of metal. The metal part of the traditional key is easily cut and copied, however the transponder is protected by an electronic chip that protects it. The chip has a unique code which is programmed into a car's computers in order to identify it.

When a saab 9-3 key not accepted contact service key fob is used, the car recognizes it and allows it to turn on. However, it will only do this if the fob is unmodified and has a chip that has been programmed to match. Otherwise, the car will reject the key and won't start.

It's important to make sure that you have a spare key for your saab key fob programming. This is particularly important especially if you reside in a rural area where there are numerous car thieves. The good news is that you can find a new key for your Saab without needing to visit a dealership and pay the high prices that they ask. You can have a replacement key created on the spot for less than half what you would pay at the dealership.

Key for Wired

Saab cars are usually delivered with two keys. If you only have one, it is recommended to purchase an additional 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 have to be replaced. This can be costly, especially for used cars.

The next step is connecting the row and columns wires to your microcontroller. This is the toughest part of the project, and it will require a lot of soldering. It's not a standard way to go about it, but you need to think about how to route and connect each column and row. There are 22 microcontroller pins and wires to connect for this keyboard. It has five rows and 17 column.

After the columns and rows are soldered, it's time to connect them to key switches. To do this you must place a diode across each key switch pin and solder it. This will protect the pins from current and prevent them from getting shorted. A diode only allows the current to flow in a single direction, and it has a black band visual indicator that indicates the direction in which current will flow.

Some of the tools you can find at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- could help customers in the shop, or even DIY customers in some cases program replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into the OBD port and guide the customer through the process, making it easier than replacing the computer in the vehicle.

Jump starting the battery

The majority of people have a set of jumper cables in their trunks to use in an emergency, but jumping a battery for newer vehicles may not be the most efficient option. These vehicles are equipped with a number of electronic devices and computers that communicate with each other. A surge in voltage when a battery is hooked up to another battery could fry these components and leave your vehicle undriveable.

Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the disabled car's hood--the engine block is a good choice. Do not connect the black cable to the negative terminal of the dead battery because this could trigger an ignition source that ignites gasoline in the engine bay.

After the cables have been connected, you can start the car and let it run about five minutes. Then disconnect the cables in reverse. The battery in your saab key replacement cost 9-3 will be recharged while you drive. It will take some time for it to drop back down. It's a good idea purchase a spare fob as soon as you can, because replacing the one that works requires the installation of a brand new computer module and special programming to convince the system that your lost keys aren't trying to steal the car.

Replacement case

saab 9-3 key programming owners usually only have one car key, and if it is lost saab keys, they will be charged. The reason is that it's not cheap to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or any other disaster it is best to have a spare key. Don't buy a secondhand key even when it's "new." Keys that are claimed-new from sellers selling aftermarket keys won't work and are likely to fail at the crucial moment.

Most locksmiths aren't able to help in the event that you only have one working key and the dealer will charge for the cost of replacing the computer in your vehicle to make a new replacement. We can, however, reset and re-program the computer's EEPROM in order to prepare it to accept a new key without replacing the entire system. This can save you a lot of money. It's cheaper to do this than waiting until you loose the only key.
