49/01-2 GROUP 80 - MODELS 203, 215 AND 220, KEY DEPENDENT MEMORY FEATURE: This is to clarify the operation of the key-dependent memory feature. This feature allows memory settings for seat position, steering column adjustment and A/C settings (203 ONLY) to be dependent upon which key is used to unlock or start the vehicle. If enabled by the customer, via the Instrument Cluster (A1) Settings display, a different memory block is used depending upon which key is used. There are a total of three (3) memory blocks available: one for key #1, one for key #2, and one shared by keys #3 through #8.
When ordering replacement keys for any reason, it is important to note that only these three memory blocks are available, and the key number ordered will affect the memory blocks available. For example, if key #1 is replaced with key #4, then the first memory block (assigned to key #1) is no longer accessible. Specifically, key #2 will use the second memory block, and keys #3 and #4 will share the third memory block. The loss of a memory block may lead to customer complaints. Therefore, if the customer wishes to retain the key dependent memory feature, replace keys #1 & 2 with the same numbered key.
A specific key may be ordered by using one of the following methods:
- The key ordering screen within PICS ordering in NetStar, specifying "DUP" and key number to be duplicated in the turnaround information field.
- Contacting Dealer Parts Services with the VIN number & included the specific key number required.
- Faxing a Parts Organization form MBNA 5020A (1-82) to 877-766-6262.
