Saab Key Programming

Saab cars built since 1994 use an immobilizer that relies on coded keys. The addition of a key requires an entirely new transponder and programming. This is usually done by the dealer using the Tech2 diagnostic tool.

It can be costly. It is always advisable to keep an extra set of keys at hand.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to the car when it is inserted into the ignition. The car is able to check whether the signal matches the one on the key. If the signals match the car will be able to unlock itself and start. This is an excellent way to protect your car from theft.

Transponder keys are a favored feature in automobiles, however it is important to know that they are not as secure as classic keys made of metal. While the metal parts of a traditional key could be cut and copied however, a transponder is secured by an electronic chip. The chip contains a unique code that is inserted into a car's computers in order to identify it.

When a saab 93 key programming key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob if it has an unmodified chip and has been programmed to match. The car will not start if the key is not programmed to match.

It is vital to have an extra saab key fob key. This is especially true when you live in a rural location where there are a lot of car burglars. You can get a new key for your saab replacement key programming by going to the dealership, without having to pay their expensive costs.

Wired key

Saab cars are usually supplied with two keys. If you have only one, you should get an additional key as fast as you can. This is because if you lose it the car will require a new CIM and the locking cylinders replaced. This can be costly especially if buying a used car.

The next step is connecting the wires for columns and row to your microcontroller. This is the most tedious part of the project and it will require lots of soldering. It's not a common way to do it, but you need to determine how to route and solder each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered together, it is time to connect the key switches. To do this, place a diode over each key switch pin and then solder it. This will shield the pins on the key switch from current and stop them from being shorted. A diode allows the current to flow in a single direction, and it comes with a an indicator of black color that indicates the direction current will flow.

A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could aid shop customers or DIY customers in certain instances program replacement key for saab 93 keys and restore the lost immobilizer's data, Sanabria says. The tools connect to OBD ports and guide the user through each step making the process simpler than replacing the vehicle's computer.

Jump starting the battery

A majority of people keep an item in their trunks to jump start a car in an emergency, however it might not be a good idea for vehicles that are newer. These cars are equipped with a variety of digital and computers that communicate with one another. A voltage spike when batteries are connected to another could cause damage to the components making your car unusable.

Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface beneath the hood of the damaged vehicle. The engine block is a good option. Don't connect the black cable to the negative terminal of the dead battery because it could ignite an ignition that ignites the gasoline in the engine bay.

Once the cables are connected the vehicle that has been disabled and let it run for about five minutes before you disconnect the cables in reverse order. The battery in your saab milton keynes 9-3 will be recharged as you drive. It takes a while for it to fall back. It's a good idea to invest in a spare key fob as soon as you can, because replacing the one that works requires the installation of a new computer module and special programming to convince it that your lost keys aren't trying to steal the car.

Replacement Case

Many Saab owners have only one key for their car and if they lose it, they'll be charged. It's costly to add an additional key and it requires replacing the CIM or TWICE in the case of older models. It is recommended to have a second key in case of theft or other disaster and the best option is to purchase a second key as soon as you are able to. Even when the key is "new" it will not function.

The majority of locksmiths won't be able to help in the event that you only have one working key and the dealer will charge top dollar to replace the computer in your car for a replacement. However, we can reset and re-program the computer's EEPROM to prepare it to accept an alternative key without replacing the whole system. This could save you lots of money. It's also less expensive than waiting until you lose the only key.
