1. The door locks will not work with the door open. That is normal.
2. Is this with only the FOB or with the switches itself?
3. Did you hold the FOB button for at least 2 seconds trying to release the trunk? Also, it could be the receiver causing the issue as well.

Condition # 1
The fuel pump currently installed on the vehicles listed above may generate electrical transients which interfere with proper operation of the Remote Keyless Entry (RKE) module. The RKE module may respond to cause one or more of the conditions stated above.
Conditions # 2 and # 3
Outside noise interference near the frequency of the RKE transmitter (key fob) to receiver (RKE module) signal may cause these conditions. Software in the RKE receiver interpreted the noise as data, allowing the possibility of condition # 2 and/or # 3 to occur. An update to the software eliminated the unwanted conditions.
To repair the above conditions, replace the RKE module with the following:
RKE module (Domestic*) - P/N 16215349 (With Date Code 05 or later) RKE module (Export) P/N 16215399 (*Includes Canada)
The RKE module date code is the left-most two digits of the number on the module connector.
Follow the module replacement procedure provided in Section 9K of the 1994 Service Manual. Refer to ON-VEHICLE SERVICE paragraph.
In 1995 model year, initial production of new RKE module, P/N 16215349, did not have the updated software described above. For those vehicles, replace RKE module, P/N 16215349, with service part RKE module, P/N 16215349, having Date Code 05 or later. The VIN breakpoints for vehicles with the new RKE module but old software in the module are as follows:
1995 Concours, DeVille - 221304 to 261820 1995 Eldorado - 604176 to 612222 1995 Seville 806148 to 818910
