E46 keys can only be purchased from accredited BMW dealerships. You can program your new E46 BMW key yourself after you receive it.

1. Use the automobile key to unlock the central locking system (ZV). The central locking system must first be activated.
2. Enter the vehicle and lock all doors.
3. Using the car key, temporarily switch the ignition lock to position 1 and then turn it off. Otherwise, the system is not prepared for initialization because the switching time must not exceed 5 seconds. You must turn the ignition switch to position 1 and insert the key.
4. Press button #2 at the radio transmitter and hold it down. Then, within five seconds of taking out the key from the ignition, push and hold button #2.
5. Three times depress button #1. The second button must be held in place. Then, with button #2 still depressed, you have up to 10 seconds to hit the Roundel button THREE times.
Releasing button #2
7. The ZV indicates that a radio transmitter has been successfully initialized by “Locking” and then immediately “Unlocking.”
You begin the programming of any extra remote keys on STEP 4 if you have any. Never put another remote key into the ignition switch; if you do, the programming for the first key will be lost.
Initialization will stop and start again if the ZV doesn’t send a return signal. Three additional radio transmitters can be initialized after the initialization process is finished. Every radio transmitter must repeat the process outlined in step 4 above within 30 seconds to avoid initialization stand-by being turned off. All other active radio transmitters must also be initialized during initialization. Never start the engine again while the initialization process is in progress. All radio transmitters would need to be re-initialized if this happened.

1. Quickly turn the key to position 1 five times. Remove the key. 3. Press the lock button three times while holding the unlock button pressed. 4. Within 30 seconds, press the same button if you have another key. 5. Start the engine to complete
Optional method 2:
1. Enter the vehicle and lock all doors and windows using both keys. 2. Turn the ignition to position 1 and insert the functional key. 3. After returning the key to position 0, remove it from the ignition. 4. Using the functional key, press the BMW logo (lock button) three times while maintaining pressure on the unlock button. Ideally, doors lock and unlock. 5. Using the new key, press the BMW logo (lock button) three times while holding down the unlock button, then release the unlock button.

Can a BMW key be duplicated?
BMW remains the most stolen car in the UK despite all discussions on the internet and TV shows, and tragically, thieves are constantly working to reverse engineer its software. Two techniques are used to copy keys. The most popular technique involves breaking the driver’s window or picking the door lock; after doing so, the burglar will reach their arm through the window and connect a small, black box to the car’s OBD port. A new key will be copied into the vehicle within 30 seconds. This new key will operate the vehicle’s door locks and start/stop it.
The other way involves burglars using cutting-edge equipment to scan for nearby keyless entry keys. After duplicating your key, they can approach your car and depress a button. Once the doors are unlocked, they can start the car and drive off. Customers believing that their remote won’t broadcast a signal if they don’t push a button is the main issue.

Reprogramming Chip keys is possible?
To curb auto thefts, automotive manufacturers have offered transponder car keys since 1995. The ignition of today’s cars cannot be hot wired, making it impossible for thieves to drive off in a stolen automobile. The top plastic portion of the key contains a programmable transmitter chip that is part of the transponder, chip, or smart key. The transponder in the car’s ignition receives a coded signal from the chip and decodes it. The car will now start after receiving and positively recognising the coded signal. The majority of automakers give customers two smart keys or fobs to prevent failures and loss. You can replace and/or reprogramme the new chip key or fob if you lose one or both of the keys. It is strongly advised to always keep two chip keys on hand and to swap out any that are lost or broken.

The price to reprogram a fob is determined by a number of factors. Although it’s difficult to provide a general price, reprogramming often costs between $50 and $250. Here are some elements that can affect price:
- Type of Fob: Reprogramming smart keys with a transponder (RFID), keyless ignition, or other additional features is typically more expensive.

- Vehicle Model: Within a given automaker, some models feature key fobs that are more complicated than others.
