Saab Ignition Key Replacement Key Programming

saab 93 key fob replacement cars produced since 1994 utilize an immobilizer system that is based on a set of keys. A new transponder is required to allow the addition of an additional key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

It can be costly. This is why you should always keep a spare key in your possession.

Transponder key

The transponder is a piece of key that is equipped with an electronic chip. This chip sends out a signal when the key is put in the ignition. The car checks to see whether the signal matches with the one on the key. If the signals are identical the car will then unlock itself and begin. This is a great way to avoid auto theft and keep your vehicle secure from thieves.

Transponder keys are a popular feature in vehicles, but you must be aware that they aren't as secure as classic metal keys. The metal portion of a traditional key can be easily copied and cut, but transponders have an electronic chip that guards it. This chip has a unique code 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 will only do this if the key fob has an unmodified chip that has been programmed to match the original. The car will not start in the event that the key has not been programmed to match.

It is essential to ensure that you have a spare key for your Saab. This is especially true especially if you reside in a rural region where there are a lot of car thieves. You can obtain a replacement key for your Saab by going to the dealership, without having to pay their pricey prices. You can get a replacement key created on the spot for less than half the cost you would pay at an auto dealer.

Key for Wired

Saab cars are usually provided with two keys. If you have only one, it is recommended to get an additional key as quickly as you can. This is because, if it's lost, the car will need a new CIM and the locking cylinders replaced. This can be costly, especially if you are buying a used car.

The next step is connecting the wires of columns and row to your microcontroller. This is the most difficult part of the project and will require a large deal of soldering. There isn't a standard way to accomplish this, however it's important to plan out how you will route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.

Once the rows and columns are soldered, it's the 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 stop them from being shorted. The diode allows current to only flow in only one direction. It has a visual indicator with a black band that shows which way current will flow.

Some of the tools you can find at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- could help customers in the shop, or even DIY customers in certain instances create replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into OBD ports and guide the user through each step, making the process easier than replacing the vehicle's computer.

Jump-starting the battery

The majority of people have the set in their trunk to jump start a vehicle in the event of an emergency, but this might not be the best idea for vehicles that are newer. These vehicles are equipped with many digital and computer systems that communicate with each other. A voltage spike when the battery is connected another can fry the components and render your vehicle unusable.

Connect the cables to the vehicle that is operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface under the disabled vehicle's hood. An engine block is a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks, which would ignite the gasoline in the engine compartment.

Once the cables are connected the vehicle that is disabled and allow it to run for around five minutes before disconnecting them in reverse order. Be aware that the battery of your Saab 9-3 is charged when you drive, so it could take a while to get the battery back to its original level. You should invest in a second key fob, as soon as you can. Replacing the 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'll be charged. The reason is that it's not inexpensive to add a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's best to have a spare key in the event of theft or any other catastrophe the best solution is to buy an extra key as early as you can. Don't buy a secondhand key even it's "new." Keys that are claimed to be new from a second-hand store will not perform and are almost certain to fail at the crucial moment.

The dealer will charge you the most expensive dollar if you only have one working key. We can reset and reprogram the EEEPROM of your computer for it to accept a new key without replacing the entire system. This could save you a great deal of money. It's less expensive rather than wait until you lose your only key.
